perf/x86/rapl: Fix Haswell and Broadwell server RAPL event
Perf-fuzzer triggers non-existent MSR access in RAPL driver on
Haswell-EX.
Haswell/Broadwell server and client have differnt RAPL events.
Since 'commit 7f2236d0bf9a ("perf/x86/rapl: Use Intel family macros for
RAPL")', it accidentally assign RAPL client events to server.
