qeth: display service_level info only when valid.

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

qeth displayed an entry in /proc/service_level even when no valid
MCL-string was available (the MCL info is blank). The change is to
create an entry in /proc/service_level only when MCL-string is
non-zero.
