Use the explicit DAX flag instead of checking the inode flag in the
iomap code.

Any particular reason to pass this in as a flag vs. querying the inode?

Same reason as the addition of IOMAP_DAX.  But I think I'll redo this
a bit to do the XFS paramater passing first and then actually check
IOMAP_DAX together with introducing it to make it all a little more clear.
