scsi: default to scsi-mq



Remove the SCSI_MQ_DEFAULT config option and default to the blk-mq I/O
path now that we had plenty of testing, and have I/O schedulers for
blk-mq.  The module option to disable the blk-mq path is kept around for
now.

		This option enables the new blk-mq based I/O path for SCSI
		devices by default. With the option the scsi_mod.use_blk_mq
		module/boot option defaults to Y, without it to N, but it can
		still be overridden either way.

		If unsure say N.
