res_counter: Merge res_counter_charge and res_counter_charge_nofail
These two functions do almost the same thing and duplicate some code. Merge their implementation into a single common function. res_counter_charge_locked() takes one more parameter but it doesn't seem to be used outside res_counter.c yet anyway. There is no (intended) change in the behaviour.
