ext4_mb_update_group_info is only called in one place, and it's
extremely simple.  There's no reason to have it in a separate
function in a separate file as far as I can tell, it just
obfuscates what's really going on.

Perhaps it was intended to keep the grp->bb_* manipulation
local to mballoc.c but we're already accessing other grp->
fields in balloc.c directly so this seems ok.
