ext4: fix online resize with mballoc
Update group infos when updating a group's descriptor. Add group infos when adding a group's descriptor. Refresh cache pages used by mb_alloc when changes occur. This will probably need modifications when META_BG resizing will be allowed. Signed-off-by: Frederic Bohe <frederic.bohe@bull.net> Signed-off-by: Mingming Cao <cmm@us.ibm.com>
