tune2fs: more respect for quota config option
Commit
44a2cca3 disabled tune2fs -O quota when the build
didn't have --enable-quota at configure time, but that
wasn't quite enough.
We need to exclude the "-Q" option as well from tune2fs
when --enable-quota isn't specified at configure time.
Otherwise, tune2fs -Q can set the quota feature, but no other
utility will touch the filesystem due to the unknown flag,
if buitl w/o --enable-quota.
So put everything related to "-Q" under #ifdef CONFIG_QUOTA;
usage output (was missing before) and option parsing.
