[SCSI] mpt fusion: config path optimized, completion queue is used

Browse Source 
1) 	Previously we had mutliple #defines to use same values.
	Now those #defines are optimized.
	MPT_IOCTL_STATUS_* is removed and  MPT_MGMT_STATUS_* are new
	#defines.
2.)	config path is optimized.
	Instead of wait Queue and timer, using completion Q.
3.)	mpt_timer_expired is not used.

[jejb: elide patch to eliminate mpt_timer_expired]
