Small Buffer wolfSCP 

When using a small file buffer for SCP, there was a combination of file
size and channel window size where SCP would read the remainder of the
file, close it, send a small message because the peer's window was full,
then try reading the file again. The change keeps trying to send if the
file buffer still has data.
