x86/perfc: add hypercall performance counters for hvm, correct pv

The HVM hypercall handler is missing incrementing the per hypercall
counters. Add that.

The counters for PV are handled wrong, as they are not using
perf_incra() with the number of the hypercall as index, but are
incrementing the first hypercall entry (set_trap_table) for each
hypercall. Fix that.
