staging: lustre: fix quotactl permission denied (LU-4530)

Browse Source 
The changes introduced in commit 4b1a25f06b ("fix build when
CONFIG_UIDGID_STRICT_TYPE_CHECKS is on") got the UID check the wrong way
around, leading to "Permission denied" when a regular user attempts to
retrieve his quota (lfs quota -u ...) but allowing him to retrieve other
users quota.

Full details at: https://jira.hpdd.intel.com/browse/LU-4530
