[PATCH 2/3] Fix issue where cli socket buffer may get full

[Kenth Eriksson]

The cli module must reset the socket io buffer rpos when all characters
in the socket buffer has been processed.

The method cli_get_command is always invoked twice for every CLI
command, thus rxpos may also be reset at the second invocation if no
newline was found and no new data is input to the socket buffer.
