Fix memory leak in mmc_read()
There is be a path through mmc_read in drivers/mmc/mmc.c where malloc'd memory is not freed before exiting mmc_read: it occurs if mmc_set_blocklen() returns a non-zero value. Reported-by: Quentin Armitage <Quentin@Armitage.org.uk> Signed-off-by: Wolfgang Denk <wd@denx.de>
