lfs quota (without -g option) doesn't show correct group quota information

# lfs quota /lustre/
Disk quotas for usr root (uid 0):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
       /lustre/   13208       0       0       -    1096       0       0       -
Disk quotas for grp root (gid 0):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
       /lustre/       0       0       0       -       0       0       0       -

* kbytes(0 is dispolayed) should be 13208

# lfs quota -g root /lustre/
Disk quotas for grp root (gid 0):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
       /lustre/   13208       0       0       -    1096       0       0       -

This is because, on the server side GETQUOTA is not executed when oqctl->qc_dqblk.dqb_curspace not 0. So, qctl.qc_dqblk need to be cleared to display correct.

static int quotactl_ioctl(struct ll_sb_info *sbi, struct if_quotactl *qctl)
{
<snip>
                if (cmd == Q_GETQUOTA &&
                    !(oqctl->qc_dqblk.dqb_valid & QIF_SPACE) &&
                    !oqctl->qc_dqblk.dqb_curspace) {
