x86/power: Fix kernel-doc warnings in cpu.c

Fixes the following kernel-doc warnings:

 arch/x86/power/cpu.c:76: warning: Function parameter or
  member 'ctxt' not described in '__save_processor_state'
 arch/x86/power/cpu.c:192: warning: Function parameter or
  member 'ctxt' not described in '__restore_processor_state'
