Frederic Weisbecker 605bfaee90 hw-breakpoints: Simplify error handling in breakpoint creation requests 
This simplifies the error handling when we create a breakpoint.
We don't need to check the NULL return value corner case anymore
since we have improved perf_event_create_kernel_counter() to
always return an error code in the failure case.
