[PATCH] locking/static_keys: make old_true_key and old_false_key static

[Jason Yan]

Fix the following sparse warning:

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?
