gfs2: use a folio inside gfs2_jdata_writepage()

Patch series "gfs2/buffer folio changes for 6.5", v3.

This kind of started off as a gfs2 patch series, then became entwined with
buffer heads once I realised that gfs2 was the only remaining caller of
__block_write_full_page().  For those not in the gfs2 world, the big point
of this series is that block_write_full_page() should now handle large
folios correctly.


This patch (of 14):

Replace a few implicit calls to compound_head() with one explicit one.
