mmc: block: Fix error path of mmc_blk_alloc_req()



In case of any error within mmc_blk_alloc_req(), the bitmaps
that keep track of devices are not getting cleared. This may
result in failure to detect a card in case it reaches maximum
devices limitation. Fix it by clearing those bitmaps appropriately.
