A device disconnection (when the adb connection is closed) makes the
read() on the "receiver" socket fail.
Since commit 063a8339ed27b94a8fe1e53a284507eb2d044e15, this is reported
as an error. As a consequence, scrcpy fails with:
ERROR: Controller error
instead of:
WARN: Device disconnected
To fix the issue, report a device disconnection in that case.
