Ulf Hansson 5fff08f459 mmc: sdio: Fix potential NULL pointer error in mmc_sdio_init_card() ... commit f04086c225 upstream. During some scenarios mmc_sdio_init_card() runs a retry path for the UHS-I specific initialization, which leads to removal of the previously allocated card. A new card is then re-allocated while retrying. However, in one of the corresponding error paths we may end up to remove an already removed card, which likely leads to a NULL pointer exception. So, let's fix this.
