drop_monitor: Add error code to detect duplicate state changes
Patch to add -EAGAIN error to dropwatch netlink message handling code.
-EAGAIN will be returned anytime userspace attempts to transition the state of
the drop monitor service to a state that its already in. That allows user space
to detect this condition, so it doesn't wait for a success ACK that will never
arrive. Tested successfully by me
