Zhe Weng 31b65844a2 usrsock: Do not return error when conn not found for an event 
There might be some cases that we receive an event after socket is closed because of out-of-ordered rpmsg, since it may not cause problem, we may omit the error.
Also change log level to err when returning negated errno, because if we return negated errno, we'll directly trigger RPMSG_ASSERT outside, so we need at least an error message to indicate the reason.
