Input: psmouse - make sure we don't schedule reconnects after cleanup

Set state of the device as "initializing" during and after cleanup
to ensure that unsolicited data from the device is not passed on.
We especially want to avoid processing new device announcements
"0xaa 0x00" that can come up before we perform reconnect operation.
