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.

Calling back into the host driver directly from mmc_request_done when
doing error handling were just plain wrong.
This patch is really great, not just for pm_runtime issues!
