[SCSI] qla2xxx: Don't explicitly read mbx registers while processing a system-error.
Callers of qla2x00_async_event() already populate the mb[] array
upon invocation, doing so via the appropriate mailbox register
accessors. The stale codes removed are leftover-bits kept during
the FWI2 transition. Though relatively benign, the extra-reads
are not valid for FWI2 boards (ISP24xx and above) and peek into
the incorrect regions of registers.
