ruby: network: drop member m_in_use

This member indicates whether or not a particular virtual network is in use.
Instead of having a default big value for the number of virtual networks and
then checking whether a virtual network is in use, the next patch removes the
default value and the protocol configuration file would now specify the
number of virtual networks it requires.

Additionally, the patch also refactors some of the code used for computing the
virtual channel next in the round robin order.
