When building with -Wmissing-prototypes without CONFIG_GENERIC_BUG,
there is a warning about a missing prototype for is_valid_bugaddr():
arch/s390/kernel/traps.c:46:5: warning: no previous prototype for 'is_valid_bugaddr' [-Wmissing-prototypes]
46 | int is_valid_bugaddr(unsigned long addr)
| ^~~~~~~~~~~~~~~~
The prototype is only declared with CONFIG_GENERIC_BUG, so only define
the function under the same condition to clear up the warning, which
matches other architectures.
