gfs2: Convert gfs2_page_mkwrite() to use a folio

Convert the incoming page to a folio and use it throughout, saving
several calls to compound_head().  Also use 'pos' for file position
rather than the ambiguous 'offset' and convert 'length' to type size_t
in case we get some truly ridiculous sized folios in the future.  This
function should now be large-folio safe, but I may have missed
something.
