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.
