description:
Remove assertion that the lock isn't held

It's useless in this case, because without it we can know that
the lock is held or not on a next lock acquisition and even more
if LOCKDEBUG is enabled a failure on the acquisition will provide
useful information for debugging while an assertion failure will
provide just the fact that the assertion failed.
