s390/qeth: fix initialization on old HW
I stumbled over an old OSA model that claims to support DIAG_ASSIST,
but then rejects the cmd to query its DIAG capabilities.
In the old code this was ok, as the returned raw error code was > 0.
Now that we translate the raw codes to errnos, the "rc < 0" causes us
to fail the initialization of the device.
The fix is trivial: don't bail out when the DIAG query fails. Such an
error is not critical, we can still use the device (with a slightly
reduced set of features).
