Christoph Hellwig 2bf6e35354 xfs: fix rtalloc rotoring when delalloc is in use ...

If we're trying to allocate real space for a delalloc reservation at
offset 0, we should use the rotor to spread files across the rt volume.

Switch the rtalloc to use the XFS_ALLOC_INITIAL_USER_DATA flag that
is set for any write at startoff to make it match the behavior for
the main data device.

Based on a patch from Darrick J. Wong.
