This makes lockdep work for crosslock which is a lock allowed to
be released in a different context from the acquisition context.
Normally a lock must be released in the context acquiring the lock.
However, relexing this constraint helps synchronization primitives
such as page locks or completions can use the lock correctness
detector, lockdep.
