Christoph Hellwig 0db22d7ee4 xfs: document another racy GC case in xfs_zoned_map_extent ...

Besides blocks being invalidated, there is another case when the original
mapping could have changed between querying the rmap for GC and calling
xfs_zoned_map_extent.  Document it there as it took us quite some time
to figure out what is going on while developing the multiple-GC
protection fix.
