A remote endpoint should not need to know when a client socket is freed
if the socket never established commnication with the endpoint. Add a
mode to keep track of which endpoints a socket communicates with.
There are three modes a socket can be in:
INIT - Socket has no

There is a race for clients that open sockets before the control port
is bound. If a client gets an idr that was allocated before the control
port is bound, there is a chance the previous address owner sent lookup
packets to the control port. The new address owner will get residua

In order to prevent intent build up, deny intent requests that can be
fulfilled by default intents that are reusable.

Un-register and register of rpmsg driver is sending invalid open_ack
on closed channel.
To avoid sending invalid open_ack case unregister the rpmsg device
after receiving the local_close_ack from remote side.
