4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mathieu Malaterre <malat@debian.org>

commit 81bd415c91eb966118d773dddf254aebf3022411 upstream.

The split out of the hard lockup detector exposed two new weak functions,
but no prototypes for them, which triggers the build warning:

  kernel/watchdog.c:109:12: warning: no previous prototype for ‘watchdog_nmi_enable’ [-Wmissing-prototypes]
  kernel/watchdog.c:115:13: warning: no previous prototype for ‘watchdog_nmi_disable’ [-Wmissing-prototypes]

Add the prototypes.
