quota: Allow Q_GETQUOTA for frozen filesystem

jankara · jankara · commit 7955118eafc4 · 2016-02-09T13:05:23.000+01:00
quota_cmd_write() forgot to list Q_GETQUOTA among commands allowed for
frozen filesystem. Thus Q_GETQUOTA quotactl would unnecessarily block
on frozen filesystems. Fix the issue by properly listing Q_GETQUOTA.
