Subject: rpmsg: qcom_smd: Correct return value for O_NONBLOCK

From: Bjorn Andersson <[email protected]>

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.
