HID-D: Don't always remove pairing on reception of VC unplug

This patch prevents DUT acting as HID Device from removing bond related
information of remote device, on reception of virtual cable unplug in
cases when some other profiles apart from HID are also connected on same
ACL on which hid profile is connected. Wihtout this patch it was observed
that other profiles were also getting disconnected when DUT started
unpairing process on reception of VC unplug. Now bonding information
would be removed only when HID is the only profile connected on same
ACL when VC unplug is sent/received on HID Device side.

HID: Prevent freeing buffer twice during set report

This patch fixes freeing of buffer twice during set report. Buffer is
already freed by l2cap layer while sending data to hci layer, so
freeing the same buffer using GKI_freebuf was resulting in warning
exception. Now buffer is just assigned to NULL so that it can be reused
again without the need to free again on reception of handshake event
for set report.
