Cyrill Gorcunov 1ea5a6afd9 perf, x86: P4 PMU - Don't forget to clear cpuc->active_mask on overflow 
It's not enough to simply disable event on overflow the
cpuc->active_mask should be cleared as well otherwise counter
may stall in "active" even in real being already disabled (which
potentially may lead to the situation that user may not use this
counter further).

Don pointed out that:

 " I also noticed this patch fixed some unknown NMIs
   on a P4 when I stressed the box".
