udf: Remove dead quota code
Quota on UDF is non-functional at least since 2.6.16 (I'm too lazy to do more archeology) because it does not provide .quota_write and .quota_read functions and thus quotaon(8) just returns EINVAL. Since nobody complained for all those years and quota support is not even in UDF standard just nuke it. Signed-off-by: Jan Kara <jack@suse.cz>
