quota: Use %pV and __attribute__((format (printf in __quota_error and fix fallout
Use %pV in __quota_error so a single printk can not be interleaved with other logging messages. Add __attribute__((format (printf, 3, 4))) so format and arguments can be verified by compiler. Make sure printk formats and arguments match. Block # needed a pointer dereference. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jan Kara <jack@suse.cz>
