linux: Handle device disconnection early when possible
If a device is open, the device's fd will trigger a POLLERR condition
once it is removed. Sometimes this can occur well before the udev
monitor sends the remove event. This can also be caught early if
the device is not currently open but an attempt to open it is made.
In both situations, this can be caught early and processed so that
the device does not continue to show up in the device list after it
has been disconnected but before the udev monitor processes the event.
