HID: Send connection state change broadcast during cleanup

Usecase:
1) Connect HID device with DUT
2) Turn Off BT

Observation:
HID state change is not received by application leading to
application showing connected even when BT is turned off and
HID was connected.

Rootcause:
HidService does not send state change to application if BT is turned off
while connected

Fix:
Send broadcast for HID connection state change during cleanup.

Test: Verified that connection state change intent is received by upper layers
during BT off if HID was connected.
