LU-5638 tests: Skip sanity-quota tests for ZFS

LU-5638 tests: Skip sanity-quota tests for ZFS

sanity-quota tests 11, 33, 34 and 35 are failing frequently
in review-zfs-part-1 test groups. We are temporarily disabling
these tests until a fix is submitted.

Note that LU-5638 is thought to be caused by
LU-2435 inode accounting in osd-zfs is racy.
