Subject: [PATCH 5.1 127/155] scsi: qla2xxx: Reset the FCF_ASYNC_{SENT|ACTIVE} flags

[ Upstream commit 0257eda08e806b82ee1fc90ef73583b6f022845c ]

Driver maintains state machine for processing and completing switch
commands. This patch resets FCF_ASYNC_{SENT|ACTIVE} flag to indicate if the
previous command is active or sent, in order for next GPSC command to
advance the state machine.

[mkp: commit desc typo]
