[SCSI] qla2xxx: Correct PLOGI retry logic.

Original code attempts to retry PLOGIs to fcports that are
FCP_TARGETs only.  If the driver never performed a successful
PLOGI/PRLI, the port-type would never be assigned, and the
relogin logic would silently drop the request (and thus the port
would not be recognized and registered).

The fix is relatively straightforward, drop the FCP_TARGET-only
check.
