dm-verity: make real_digest and want_digest fixed-length
Change the digest fields in struct dm_verity_io from variable-length to
fixed-length, since their maximum length is fixed at
HASH_MAX_DIGESTSIZE, i.e. 64 bytes, which is not too big. This is
simpler and makes the fields a bit faster to access.
(HASH_MAX_DIGESTSIZE did not exist when this code was written, which may
explain why it wasn't used.)
This makes the verity_io_real_digest() and verity_io_want_digest()
functions trivial, but this patch leaves them in place temporarily since
most of their callers will go away in a later patch anyway.
