scsi: qla2xxx: Fix erroneous mailbox timeout after PCI error injection
Clear wait for mailbox interrupt flag to prevent stale mailbox:
Feb 22 05:22:56 ltcden4-lp7 kernel: qla2xxx [0135:90:00.1]-500a:4: LOOP UP detected (16 Gbps).
Feb 22 05:22:59 ltcden4-lp7 kernel: qla2xxx [0135:90:00.1]-d04c:4: MBX Command timeout for cmd 69, ...
To fix the issue, driver needs to clear the MBX_INTR_WAIT flag on purging
the mailbox. When the stale mailbox completion does arrive, it will be
dropped.
