[PATCH -next] locking/static_keys: Make some symbols static

From: Bixuan Cui
Date: Fri May 07 2021 - 21:51:36 EST


The sparse tool complains as follows:

lib/test_static_keys.c:15:19: warning:
symbol 'old_true_key' was not declared. Should it be static?
lib/test_static_keys.c:16:19: warning:
symbol 'old_false_key' was not declared. Should it be static?
lib/test_static_keys.c:19:1: warning:
symbol 'true_key' was not declared. Should it be static?
lib/test_static_keys.c:20:1: warning:
symbol 'false_key' was not declared. Should it be static?

This symbol is not used outside of test_static_keys.c, so this
commit marks it static.
