rpmsg: qcom_smd: Correct return value for O_NONBLOCK
commit 1d74e7ed5dc1903ac081574a9b6aa94e7ba4ad45 upstream.
qcom_smd_send() should return -EAGAIN for non-blocking channels with
insufficient space, so that we can propagate this event to user space.
Fixes: 53e2822e56c7 ("rpmsg: Introduce Qualcomm SMD backend")
