Subject: [PATCH] mmc: queue: Remove unused parameters(request_queue)

From: ChanWoo Lee <[email protected]>

In function mmc_exit_request, the request_queue structure(*q) is not used.
I remove the unnecessary code related to the request_queue structure.

It seems this is the only caller of mmc_exit_request(). It is probably
leftover from before the switch to blk-mq. However we might as well get rid
of it and just put the code directly into mmc_mq_exit_request().

The same applies to mmc_mq_init_request() and __mmc_init_request(), so might
as well tidy up those also.
