fusefrontend: disallow O_DIRECT and fall back to buffered IO
O_DIRECT accesses must be aligned in both offset and length. Due to our crypto header, alignment will be off, even if userspace makes aligned accesses. Running xfstests generic/013 on ext4 used to trigger lots of EINVAL errors due to missing alignment. Just fall back to buffered IO.
