Slightly fix bidirectional stream number allocation.

This logic is still imperfect, since it allows at most 15 bidirectional
streams out of 30 allowed by specification, but at least now those should
work better.  On the other side I don't remember I ever saw controller
supporting the bidirectional streams, so this is likely a nop change.
