watchdog/core: Add missing prototypes for weak functions 



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.
