xfs: move xfs_get_extsz_hint() and kill xfs_rw.h

The only thing left in xfs_rw.h is a function prototype for an inode function. Move that to xfs_inode.h, and kill xfs_rw.h. Also move the function implementing the prototype from xfs_rw.c to xfs_inode.c so we only have one function left in xfs_rw.c Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Mark Tinguely <tinguely@sgi.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Ben Myers <bpm@sgi.com>
