Don't deref NULL mutex pointer when pipeclose()'ing a pipe that is not

fully instaniated.

Revert the logic in pipeclose so that we don't have the entire function
pretty much under a single if() statement, instead invert the test and
just return if it fails.

Don't use pool mutexes for pipes.  We can not use pool mutexes
because we will need to grab the select lock while holding a pipe
lock which is not allowed because you may not aquire additional
mutexes when holding a pool mutex.

Instead malloc(9) space for the mutex that is shared between the
pipes.
