perf/x86/intel/uncore: Fix memory leaks on allocation failures

Currently if an allocation fails then the error return paths
don't free up any currently allocated pmus[].boxes and pmus causing
a memory leak.  Add an error clean up exit path that frees these
objects.

Detected by CoverityScan, CID#711632 ("Resource Leak")
