[PATCH blktests v5 3/5] nvme/030: only run against kernel soft target

[Aurelien Aptel <aaptel@nvidia.com>]

From: Daniel Wagner <dwagner@suse.de>

This tests is exercising the target code and not so much the host side.
The problem with nvme/030 is that it depends on interface to interact
with the target which is not covered by the standard. Thus we can't
run it against an arbitrary target. Just skip it when we run against a
arbitrary target.
