mmc_request_done() is sometimes called from interrupt or other atomic
context. Mostly all mmc_request_done() does is complete(), however it
contains code to retry on error, which uses ->request(). As the error
path is certainly not performance critical, this may be moved to the
waiting function mmc_wait_for_req_done().
This allows ->request() to use runtime PM get_sync() and guarantee it
is never in an atomic context.
