[SCSI] qla2xxx: Correct issue where incorrect init-fw mailbox command was used on non-NPIV capable ISPs.

BIT_2 of the firmware attributes is only valid on FW-interface-2
type HBAs.  Code in commit
c48339de would cause the
incorrect initialize-firmware mailbox command to be issued for
non-NPIV capable ISPs.  Correct this by reverting to previously
used (and correct) pre-condition 'if' check.
