P2P: Call normal SD query callback on RX/TX race

Browse source 
If the TX success response races with the RX frame then the state
machine was simply move to P2P_SD_DURING_FIND to continue the operation.
However, this does not take into account broadcast queries where the
callback handler updates the peer's sd_pending_bcast_queries.

Fix this by exporting the callback and calling it directly. This is
fine, as the operation is cancelled immediately afterwards, ensuring
that the callback is not called a second time.
