[SCSI] lpfc 8.3.0 : Fix issue with assumed Interrupt Enable Block support

The phba hbq_get address was setup before the HBA reported support for
Interrupt Enable Block (INB).  This caused loopback tests to fail
after all HBQs had been used once.  Moved setting of hba_get until
after config port mailbox command completes.
