mmc_block: add dev_t initialization check
When a card is removed before mmc_blk_probe() has called add_disk(), then
the minor field is uninitialized and has value 0. This caused
mmc_blk_put() to always release devidx 0 even if 0 was still in use. Then
the next mmc_blk_probe() used the first free idx of 0, which oopses in
sysfs, since it is used by another card.
