[PATCH] perf/x86/intel/rapl: fix pmus free during cleanup

[Vincent Stehlé]

On rapl cleanup path, kfree() is given by mistake the address of the
pointer of the structure to free (rapl_pmus->pmus + i). Pass the pointer
instead (rapl_pmus->pmus[i]).

This was introduced by commit 9de8d686955b0e8e27847ed4edbbcd280f3fd8
("perf/x86/intel/rapl: Convert it to a per package facility").
