ocfs2: reset folio to NULL when get folio fails
The reproducer uses FAULT_INJECTION to make memory allocation fail, which
causes __filemap_get_folio() to fail, when initializing w_folios[i] in
ocfs2_grab_folios_for_write(), it only returns an error code and the value
of w_folios[i] is the error code, which causes
ocfs2_unlock_and_free_folios() to recycle the invalid w_folios[i] when
releasing folios.
