Mark res_counter_charge(_locked) with __must_check
Ignoring their return values may result in counter underflow in the future -
when the value charged will be uncharged (or in "leaks" - when the value is
not uncharged).
This also prevents from using charging routines to decrement the
counter value (i.e. uncharge it) ;)
(Current code works OK with res_counter, however :) )
