Subject: [PATCH] sched/wait: Clean up some documentation warnings

References: bnc#971975 VM performance -- page waitqueue
Patch-mainline: v4.13-rc3
Git-commit: 6c423f5751b9f68bfe7c7545519d4c7159f93e1b

A couple of kerneldoc comments in <linux/wait.h> had incorrect names for
macro parameters, with this unsightly result:

  ./include/linux/wait.h:555: warning: No description found for parameter 'wq'
  ./include/linux/wait.h:555: warning: Excess function parameter 'wq_head' description in 'wait_event_interruptible_hrtimeout'
  ./include/linux/wait.h:759: warning: No description found for parameter 'wq_head'
  ./include/linux/wait.h:759: warning: Excess function parameter 'wq' description in 'wait_event_killable'

Correct the comments and kill the warnings.
