Existing code uses lockf to ensure exclusive PMC access of one process and
one TraceId. However Thunk spec allows hsaKmtPmcAcquireTraceAccess to get
exclusive access to the defined set of counters, not exclusive to one
process or one TraceId. Multiple counter sets of multiple TraceIds is
allowed if they meet the concurrent access limit evaluated by the hardware
/driver.
