mmc: core: Fixup Oops for SDIO shutdown Commit "mmc: core: Handle card shutdown from mmc_bus" introduced an Oops in the shutdown sequence for SDIO. The drv pointer, does not exist for SDIO since the probing of the SDIO card from the mmc_bus perspective is expected to fail by returning -ENODEV. This patch adds the proper check for the pointer before calling it.
