kernel, cpu: Remove bogus __ref annotations 



cpu_chain lost its __cpuinitdata annotation long ago in commit
5c113fbe ("fix cpu_chain section mismatch..."). This and the global
__cpuinit annotation drop in v3.11 vanished the need to mark all users,
including transitive ones, with the __ref annotation. Just get rid of it
to not wrongly hide section mismatches.
