ISP2200 adapters only have 24 mailbox registers so read only that many.

Subject: [SCSI] qla2xxx: Remove check for null fcport from host reset handler.

Remove the check for a NULL fcport so that the host reset will run
unconditionally to unwedge any commands before the device is offlined and to
prevent a quick runthrough of the SCSI error handling.

Subject: [SCSI] qla2xxx: Cache swl during fabric discovery.

Rather than continuously allocating and freeing swl within the discovery
process, simply pre-allocate it the first time that it's needed, cache it
through the rest of the lifecycle of the driver and free it at module unload.

Subject: [SCSI] qla2xxx: Add ha->max_fibre_devices to keep track of the
 maximum number of targets.

Add a field to the qla_hw_data struct to allow us to set the maximum number of
fabric devices on a per adapter basis based on ISP type.

Subject: [SCSI] qla2xxx: handle default case in qla2x00_request_firmware()

This silences a static checker warning.  Also we're always adding new
types of firmware, so it might fix a bug in real life some day.
