When a fd is removed dev->state gets set to device_state_removed,
if the fd then gets re-added before InputThreadDoWork() deals with
the removal, the InputThreadDevice struct gets reused, but its
state would stay device_state_removed, so it would still get removed
on the first InputThreadDoWork() run, resulting in a non functioning
input device.
This commit fixes this by (re-)setting dev->state to device_state_running
when a InputThreadDevice struct gets reused.
This fixes input devices sometimes no longer working after a vt-switch.
