Dont show "Erase SD Card" when there is none

On devices with physcal, external SD Cards, the "Erase SD card"
option in in Settings/Storage is available even when there is
no SD card present, this dont make much sense since you cannot
erase a card that is absent. With this change the erase option
is bound to the mount toggle which leads to the following
consequences:

 Card present and mounted -> Erase enabled
 Card present but unmounted -> Erase enabled
 No card present -> Erase disabled
 Card present and MTP attached -> Erase disabled

Bluetooth: HID: Use proper values of connection status

This patch fixes issue in retrieving correct connection status when
more than one hid device was connected to DUT. In such situation
current implementation was sending STATE_DISCONNECTED as connection
state because of wrong check of matching device as 1st device in
connected device list. Instead of this now actual connection state
device is retrieved from HidService.

Bluetooth: disable scan icon when BT state is off

Usually onScanningStateChanged function should take care
of disabling the scan icon when the scan is completed.

But When the BT scan is going on and try to switch of the
BT, as onScanningStateChanged function doesn't have the
reference for scan icon it will not disable it, so disabling
is taken care in BluetoothSettings on receiving BT Off state.

On receiving BT Off state, disable the scan progress icon only
when available device category is present.
