jbd2: avoid -Wempty-body warnings
Building with 'make W=1' shows a harmless -Wempty-body warning:
fs/jbd2/recovery.c: In function 'fc_do_one_pass':
fs/jbd2/recovery.c:267:75: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
267 | jbd_debug(3, "Fast commit replay failed, err = %d\n", err);
| ^
Change the empty dprintk() macros to no_printk(), which avoids this
warning and adds format string checking.
