lockdep: Move lockdep_assert_locked() under #ifdef CONFIG_PROVE_LOCKING
When lockdep_assert_locked() is unused, it prevents kernel builds
with clang, `make W=1` and CONFIG_WERROR=y, CONFIG_LOCKDEP=y and
CONFIG_PROVE_LOCKING=n:
kernel/locking/lockdep.c:160:20: error: unused function 'lockdep_assert_locked' [-Werror,-Wunused-function]
Fix this by moving it under the respective ifdeffery.
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
[Boqun: add more config information of the error]
