net: qrtr: mhi_dev: Only post valid data



mhi_dev_read_channel returns the number of bytes read. Do not post a
packet to qrtr if the length returned is 0. This prevents an issue
where qrtr receives duplicates packets from the mhi_dev transport.

commit net: qrtr: mhi_dev: Only post valid data
(b4451ceb04138).
