[SCSI] mptsas : set max_id to infinite value.
Do not set max_id value received from FW. Once SAS transport layer is introduced max_id value is missleading to SCSI mid layer. Use max_id to infinite value. logic of can queue of scsi host is changed. Signed-off-by: James Bottomley <James.Bottomley@suse.de>
