qcacld-3.0: Avoid sending P2P action frame confirmation twice

qcacld-2.0 to qcacld-3.0 propagation..

P2P action frame confirmation can be called from work queue
wma_mgmt_tx_ack_work_handler as well as from MC thread during
remain on channel completion. So it can lead to race condition
where frame confirmation is called twice and driver tries to free
frame buffer twice.

To detect duplicate use PE global lock in P2P action frame
confirmation.
