commit 99b4ddd8b76a6f60a8c2b3775849d65d21a418fc upstream.
Upfront in mmc_rescan() we use the host->rescan_entered flag, to allow scanning only once for non-removable cards. Therefore, it's also not possible that we can have a corresponding card bus attached (host->bus_ops is NULL), when we are scanning non-removable cards.
For this reason, let' drop the check for mmc_card_is_removable() as it's redundant.
