Jan Rybar 08aa15ce4b sysctl: Return non-zero if param setting failed ...

Real usecase:
'sysctl -w user.max_uts_namespaces=2147483648; echo $?'
returns 0 even though it failed with EINVAL

The close_stream() realised there was an issue and printed an
error but didn't change the return value.

Slightly modified merge request.
