Default GFS2: panics on quotacheck update

From: Abhijith Das <adas@redhat.com>

Handle block allocation for forceful unstuffing of quota dinode during quota
update using quotactl(). Also fix block reservation for special cases when
quotas cross over block boundaries and update 2 blocks instead of 1.
