[PATCH] mmc: sd: Cleanup redundant memset

[Mark Asselstine <asselsm@gmail.com>]

The clearing of mrq via a memset at the top of the for loop in
mmc_wait_for_app_cmd() is not required as mrq is not used and
there is another clearing of mrq just below. We remove the first
memset since if the initial tests in the for loop fail the memset
is not required.
