Subject: watchdog: hpwdt: fix unused variable warning

From: Arnd Bergmann <[email protected]>

commit aeebc6ba88ba3758ad95467ff6191fabf2074c13 upstream.

The new hpwdt_my_nmi() function is used conditionally, which produces a harmless warning in some configurations:

drivers/watchdog/hpwdt.c:478:12: error: 'hpwdt_my_nmi' defined but not used [-Werror=unused-function]

This moves it inside of the #ifdef that protects its caller, to silence the warning.
