[PATCH 3/5] xfs: fix zoned write iomap flags assignments

[Christoph Hellwig <hch@lst.de>]

Don't overwrite IOMAP_F_DIRTY with IOMAP_F_ANON_WRITE, but ensure both
flags are set instead.

Note that in practice this is harmless as all zoned writes force a metadata
transaction anyway, but incorrectly assigned flags are still a landmine
that will cause problems at some point.

Fixes: 058dd70c65ab ("xfs: implement buffered writes to zoned RT devices")
Fixes: 2e2383405824 ("xfs: implement direct writes to zoned RT devices")
