gfs2: Fix marking bitmaps non-full
[ Upstream commit ec23df2b0cf3e1620f5db77972b7fb735f267eff ]
Reservations in gfs can span multiple gfs2_bitmaps (but they won't span
multiple resource groups). When removing a reservation, we want to
clear the GBF_FULL flags of all involved gfs2_bitmaps, not just that of
the first bitmap.
