mmc: initialize struct mmc_request at declaration time
Converts from: struct mmc_request mrq; memset(&mrq, 0, sizeof(struct mmc_request)); to: struct mmc_request mrq = {0}; because it's shorter, as performant, and easier to work out whether initialization has happened. Signed-off-by: Chris Ball <cjb@laptop.org>
