scsi: lpfc: Fix list_entry null check warning in lpfc_cmpl_els_plogi()

Smatch called out a warning for null checking a ptr that is assigned by
list_entry(). list_entry() does not return null and, if the list is empty,
can return an invalid ptr. Thus, the !psrp check does not execute properly.

 drivers/scsi/lpfc/lpfc_els.c:2133 lpfc_cmpl_els_plogi()
 warn: list_entry() does not return NULL 'prsp'

Replace list_entry() with list_get_first(), which does a list_empty() check
before returning the first entry.
