block: add a sanity check for non-write flush/fua bios
Check that the PREFUSH and FUA flags are only set on write bios,
given that the flush state machine expects that.
[Damien] The check is also extended to REQ_OP_ZONE_APPEND operations as
these are data write operations used by btrfs and zonefs and may also
have the REQ_FUA bit set.
