cmd_mmc.c: check mmc_init() during mmc dev
mmc dev ${devnum} will return 0 as success even if there is no card
inserted. Booting script like tegra-common-post.h will call mmc dev
${devnum} to check the mmc device status, it always return 0 even if
mmc_init() fails.
Check mmc_init() return value let mmc dev command return failure
when mmc_init() fails.
