xfs: support CoW in fsdax mode
In fsdax mode, WRITE and ZERO on a shared extent need CoW performed.
After that, new allocated extents needs to be remapped to the file. So,
add a CoW identification in ->iomap_begin(), and implement ->iomap_end()
to do the remapping work.
[akpm@linux-foundation.org: make xfs_dax_fault() static]
