usb: usbtest: add a test case to support bos for queue control

In Test 10 of usbtest module, it queues multiple control messages and
thereby tests control message queuing, protocol stalls, short reads, and
fault handling. And this patch add a test case to support queue BOS control
request for USB 3.0 SPEC.

usb: usbtest: fix the bit mask of usb 2.0 extension descriptor

USB 2.1 Link PM adds to use bits[1:15] according to USB 2.0 ECN Errata for
Link Power Management spec.

Bit	Encoding
0	Reserved
1	LPM
2	BESL & Altemate HIRD definitions supported
3	Recommended Baseline BESL valid
4	Recommended Deep BESL valid
11:8	Recommended Baseline BESL value
15:12	Recommended Deep BESL value
31:16	Reserved

So fix the bit mask from 0x1e to 0xfffe.

usb: usbtest: update bos test coverage to usb 2.1 device

The commit "usb: usbtest: support bos descriptor test for usb 3.0"
introduced a test for bos descriptor. And USB 2.1 device also can be
checked. So this patch extends the test coverage to support USB 2.1 device.

usb: usbtest: Always clear halt else further tests will fail

In test_halt() we set an endpoint halt condition and return on halt verification
failure, then the enpoint will remain halted and all further tests related
to that enpoint will fail. This is because we don't tackle endpoint halt error condition
in any of the tests. To avoid that situation, make sure to clear the
halt condition before exiting test_halt().

usbtest: Fix BOS control test for USB 2.01 devices.

Commit c952a8ba7136505cd1ca01735cc748ddc08c7d2f "usb: usbtest: add a
test case to support bos for queue control" will cause USB 2.01 and USB
2.10 devices with a BOS descriptor to fail case 15 of the control test.

The Link PM errata (released in 2007, updated in 2011) says:

"The value of the bcdUSB field in the standard USB 2.0 Device Descriptor
is used to indicate that the device supports the request to read the BOS
Descriptor (i.e.  GetDescriptor(BOS)). Devices that support the BOS
descriptor must have a bcdUSB value of 0201H or larger."

The current code says that non-SuperSpeed devices *must* return -EPIPE,
as this comment shows:

                /* sign of this variable means:
                 *  -: tested code must return this (negative) error code
                 *  +: tested code may return this (negative too) error code
                 */
                int                     expected = 0;

This means the test will fail with USB 2.01 and USB 2.10 devices that
provide a BOS descriptor.  Change it to only require a stall response if
the USB device bcdUSB is less than 2.01.
