[PATCH] kernel/watchdog.c - make variables static

["Valdis Klētnieks" <valdis.kletnieks@vt.edu>]

sparse complains:
  CHECK   kernel/watchdog.c
kernel/watchdog.c:45:19: warning: symbol 'nmi_watchdog_available' was not declared. Should it be static?
kernel/watchdog.c:47:16: warning: symbol 'watchdog_allowed_mask' was not declared. Should it be static?

They're not referenced by name from anyplace else, make them static.
