qla2xxx: Remove dependency on hardware_lock to reduce lock contention.
Sessions management (add, deleted, modify) currently are serialized through the hardware_lock. Hardware_lock is a high traffic lock. This lock is accessed by both the transmit & receive sides. Sessions management is now moved off to another lock call sess_lock. This is done to reduce lock contention and increase traffic throughput.
