scsi: qla2xxx: Fix link failure in NPIV environment

Browse Source 
User experienced symptoms of adapter failure in NPIV environment. NPIV
hosts were allowed to trigger chip reset back to back due to NPIV link
state being slow to come online.

Fix link failure in NPIV environment by removing NPIV host from directly
being able to perform chip reset.
