gfs2: Use b_folio in gfs2_log_write_bh()

Matthew Wilcox (Oracle) · Andreas Gruenbacher · commit 6576742b9084 · 2025-03-10T18:15:39.000+01:00
We are preparing to remove bh-&gt;b_page.  gfs2_log_write() should continue
to operate on pages as some of the memory being logged does not come
from folios, so convert from folio to page in this function.
