staging: usbip: vhci: handle EAGAIN from SO_RCVTIMEO
If there is a receive timeout without any active
requests, we can tell the connection was idle and
ignore the timeout.
If there are active requests for which we expect
to receive a reply we close the connection.
This makes it possible to set an upper bound on
the time a usbip device may be unresponsive.
This is a workaround for the lack of heart-beat
messages in the USBIP protocol.
Extending the protocol would break compatibility
with all previous stub versions, so this seems like
the lesser evil.
