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.
