hostfs: Fix the NULL vs IS_ERR() bug for __filemap_get_folio()
The __filemap_get_folio() function returns error pointers. It never returns NULL. So use IS_ERR() to check it. Fixes: 1da86618bdce ("fs: Convert aops->write_begin to take a folio") Signed-off-by: ZhangPeng <zhangpeng362@huawei.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Richard Weinberger <richard@nod.at>
