Subject: Allow all non-negative return codes as Ok()

All libssh2 functions that return a failure do so using a negative
value. However, some functions (for example:
https://www.libssh2.org/libssh2_channel_read_ex.html) might return a
positive value for success. We should recognize these positive values as
Ok() instead of Err().

This is consistent with what Stream<'channel, 'sess>::read and ::write
seem to expect in src/channel.rc.
