iomap/gfs2: Get page in page_prepare handler
Change the iomap ->page_prepare() handler to get and return a locked
folio instead of doing that in iomap_write_begin(). This allows to
recover from out-of-memory situations in ->page_prepare(), which
eliminates the corresponding error handling code in iomap_write_begin().
The ->put_folio() handler now also isn't called with NULL as the folio
value anymore.
Filesystems are expected to use the iomap_get_folio() helper for getting
locked folios in their ->page_prepare() handlers.
