scsi: qla2xxx: Fix NVMe session down detection
When Target port transitions personality from one to another (NVMe <-->
FCP), there could be some overlap of the two where one layer is going down
while the other layer is coming up. This overlap can cause temporary I/O
error. Detect those errors/transitions and recover from them. Triggers
session tear down and allow relogin to re-drive the connection under the
following conditions:
- NVMe command error
- On PRLO + N2N (rida format 2)
