watchdog/core: Add missing prototypes for weak functions

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.
