Fixes the following W=1 kernel build warning(s):

 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'

Signed-off-by: Baokun Li <libaokun1@huawei.com>
---
V1->V2:
	Fix the formatting of this kerneldoc comment
V2->V3:
        Remove redundant 'i'
