perf/x86/intel: Plug memory leak in intel_pmu_init()
 
A recent commit introduced an extra merge_attr() call in the skylake
branch, which causes a memory leak.

Store the pointer to the extra allocated memory and free it at the end of
the function.

Fixes: a5df70c354c2 ("perf/x86: Only show format attributes when supported")
