Fail-safe dev_start() operation can be called by both the application
and the hot-plug alarm mechanism.
The installation of Rx interrupt are triggered from dev_start() in any
time it is called while actually the Rx interrupt should be installed
only by the application calls.
So, each plug-in event causes reinstallation which causes memory leak
and spoils the fail-safe Rx interrupt mechanism.
Trigger the Rx interrupt installation only when it does not exist.
