Fix the following warning:
common/spl/spl_mmc.c: In function 'spl_mmc_load_image':
common/spl/spl_mmc.c:31:24: warning: 'mmc' may be used uninitialized in this
function [-Wmaybe-uninitialized]
count = mmc->block_dev.block_read(0, sector, 1, header);
^
common/spl/spl_mmc.c:251:14: note: 'mmc' was declared here
struct mmc *mmc;
^
The fix is as simple as initializing the struct mmc *mmc to NULL,
so the subsequent functions can check if the variable is set or
not.
