When triggering PMC events in response to emulation, drop the redundant
checks on a PMC being globally and locally enabled, as the passed in bitmap
contains only PMCs that are locally enabled (and counting the right event),
and the local copy of the bitmap has already been masked with global_ctrl.
No true functional change intended.
