gfs2: Set GBF_FULL flags when reading resource group

Browse Source 
When reading a resource group from disk or when receiving the resource group
statistics from a Lock Value Block (LVB), set/clear the GBF_FULL flags of all
bitmaps in that resource group according to whether or not the resource group
is full.
