arm64: hide unused is_valid_bugaddr()

Browse source

When generic BUG() support is disabled, this function has no declaration
and no callers but causes a W=1 warning:

arch/arm64/kernel/traps.c:950:5: error: no previous prototype for 'is_valid_bugaddr' [-Werror=missing-prototypes]

Add an #ifdef that matches the one around the declaration.
