On error, drop clients and close the device only if it's still open
Fixes crashes when USB devices are disconnected, caused by an attempt
to close the already closed device: it was closed once when its ref
counter drops to zero (after the last client is disconnected) and once
with an explicit call to dev_close() on the error code-path.
