scsi: be2iscsi: Add TPE recovery feature
After UE is detected, check for recoverable error by reading
SLIPORT SEMAPHORE register. If transient parity error i.e. 0xExxx
then schedule recovery work on driver wq.
FLag this error to prevent any transactions for the duration of ue2rp to
restart polling. After that, if FW becomes ready then recover port.
Wake up processes in wq before going offline.
Wait for process to execute before cleaning up.
