fsverity: simplify fsverity_get_digest()
Instead of looking up the algorithm by name in hash_algo_name[] to get
its hash_algo ID, just store the hash_algo ID in the fsverity_hash_alg
struct. Verify at boot time that every fsverity_hash_alg has a valid
hash_algo ID with matching digest size.
Remove an unnecessary memset() of the whole digest array to 0 before the
digest is copied into it.
Finally, remove the pr_debug statement. There is already a pr_debug for
the fsverity digest when the file is opened.
