Subject: [PATCH] cryptsetup: default to no hash when keyfile is specified

For plain dm-crypt devices, the behavior of cryptsetup package is to
ignore the hash algorithm when a key file is provided. It seems wrong
to ignore a hash when it is explicitly specified, but we should default
to no hash if the keyfile is specified.
