To save architectures from needing to wrap the call in #ifdefs, add a
stub no-op version of kgdb_nmicallback(), which returns 1 if it didn't
handle anything.

In v9 this is the only kgdb dependency. I'm assuming it could go
through the arm64 tree? If that's not a good idea, we could always
change the patch ("arm64: kgdb: Roundup cpus using IPI as NMI") not to
depend on it by only calling kgdb_nmicallback() if CONFIG_KGDB is not
defined.
Changes in v9:
- Added missing "inline"
Changes in v8:
- "Provide a stub kgdb_nmicallback() if !CONFIG_KGDB" new for v8
