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.
