[PATCH 01/16] blk-crypto: Simplify check for fallback support

[Eric Biggers <ebiggers@kernel.org>]

Since blk-crypto-fallback supports all blk_crypto_keys except wrapped
keys, just check for that condition directly instead of using
__blk_crypto_cfg_supported().  With this done,
__blk_crypto_cfg_supported() is now used only for the hardware support.
