zio_checksum_to_feature() expects a zio_checksum enum not a raw property
intval, so the new checksums weren't being detected when the
ZIO_CHECKSUM_VERIFY flag got in the way.
Given a pool without feature@sha512,
zfs create -o dedup=sha512 naughty/fivetwelve_noverify_ds
would fail as expected since the raw intval would indeed be equal to
SPA_FEATURE_SHA512.
However,
zfs create -o dedup=sha512,verify naughty/fivetwelve_verify_ds
would incorrectly succeed because ZIO_CHECKSUM_VERIFY would be in the
way, the raw intval would not be a member of the enum, and
zio_checksum_to_feature() would return SPA_FEATURE_NONE, with the result
that spa_feature_is_enabled() would never be called.
This was first detected with edonr, since in that case verify is
required.
This commit clears the ZIO_CHECKSUM_VERIFY flag before calling
zio_checksum_to_feature() using the ZIO_CHECKSUM_MASK and verifies in
zio_checksum_to_feature() that ZIO_CHECKSUM_MASK has been applied by the
caller to attempt to prevent the same bug from occurring again in the
future.
