Using "blk_crypto_fallback_*" for all these variables results in some pretty
long names, e.g. "blk_crypto_fallback_crypt_ctx_cache" and
"blk_crypto_fallback_num_prealloc_crypt_ctxs".  This proposal gives the best of
both worlds; the names are properly "namespaced" but there is also a shortcut to
refer to them (struct blk_crypto_fallback *fallback = &blk_crypto_fallback).

I'd just drop the second crypt in those.

If this is going to be controversial I can just drop this patch, but I was
hoping there would be a way to make things more consistent.

I personally detest that pattern.  Not sure if that counts as
controversial or even matters :)
