oprofile/x86: fix perfctr nmi reservation for mulitplexing
commit 68dc819ce829f7e7977a56524e710473bdb55115 upstream.
Multiple virtual counters share one physical counter. The reservation
of virtual counters fails due to duplicate allocation of the same
counter. The counters are already reserved. Thus, virtual counter
reservation may removed at all. This also makes the code easier.
