Added check to know the status of any ongoing pairing status.
Use Case: Host allows incoming pairing even though outgoing pairing
is in process.
Steps:
1. Initiate bonding from Mecapp and provide pin key at Mecapp pairing
pop-up.
2. Start pairing for Logitech mouse from DUT and click on accept
pairing at mecapp pairing pop-up.
3. Give the same pin key for mecapp pairing pop-up at DUT side and
observe the behavior.
Failure: Incoming request is getting from remote and got a pop-up
for PIN request.
Root Cause: Pairing was auto accepted for remote device while
pairing was in progress with another remote device leading to
inconsistent behavior.
Fix: Rejects incoming pairing request from remote device
if already in pairing state.
Test: Tested with HID Logitech Mouse
