[PATCH v3 6/6] remove __must_check for res_counter_charge_nofail()

I picked this up from Costa's slub memcg series. For fixing added warning
by patch 4.

Subject: [PATCH 6/6] remove __must_check for res_counter_charge_nofail()

Since we will succeed with the allocation no matter what, there
isn't the need to use __must_check with it. It can very well
be optional.
