From: Eric Biggers <ebiggers@xxxxxxxxxx>
This function is trivial and is only used in one place. Having this
function is misleading because it implies that blk_crypto_register()
needs to be paired with blk_crypto_unregister(), which is not the case.
Just set disk->queue->crypto_profile to NULL directly.
