Bluetooth: Do not initiate inquiry during pairing/SDP

Retry SDP if it gets cancelled in BONDING state.
If SDP search initiated after the pairing gets cancelled, re-initiate
SDP search from the BTIF layer to ensure completion of the bonding
process.

While pairing/SDP discovery of the bonded device is in progress,
do not initiate inquiry.
