USB: serial: io_ti: fix I/O after disconnect
commit 2330d0a853da260d8a9834a70df448032b9ff623 upstream.
Cancel the heartbeat work on driver unbind in order to avoid I/O after
disconnect in case the port is held open.
Note that the cancel in release() is still needed to stop the heartbeat
after late probe errors.
Fixes: 26c78daade0f ("USB: io_ti: Add heartbeat to keep idle EP/416 ports from disconnecting")
