Ingo Molnar b68f1d2e7a perf_counter, x86: speed up the scheduling fast-path ...

We have to set up the LVT entry only at counter init time, not at
every switch-in time.

There's friction between NMI and non-NMI use here - we'll probably
remove the per counter configurability of it - but until then, dont
slow down things ...
