Global variable "net_state" is used in net_loop() state-machine. But it happens that some times the net_loop() can be called multiple times in the same call stack. For example when the netconsole is enabled and we print the message while some other net protocol is in action. Netconsole will overwrite the "net_state" and that will break the logic for earlier started protocol.
To protect the state save and restore "net_state" variable each time when we enter and exit net_loop().
