scsi: lpfc: Fix failure to delete vports when discovery is in progress

Browse Source 
Requests to delete an NPIV port may fail repeatedly if the initial request
is received during discovery.

If the FC_UNLOADING load_flag is set, then skip CT response processing for
the physical port.  This allows discovery processing for other lpfc_vport
objects to reach their cmpl routines before deleting the vport.
