Fix the following sparse warning:
kernel/kallsyms.c:457:12: warning: symbol 'arch_get_kallsym' was not
declared. Should it be static?

This is originally added by
d83212d5dd67 kallsyms, x86: Export addresses of PTI entry trampolines
by Alexander Shishkin.
The original patch has a x86 specific implementation but later
it is removed.
Maybe Alexander Shishkin can take a look?
