[PATCH v2 03/10] KVM: selftests: print a message when skipping KVM tests

From: Axel Rasmussen
Date: Wed May 19 2021 - 16:04:06 EST


Previously, if this check failed, we'd just exit quietly with no output.
This can be confusing, so print out a short message indicating why the
test is being skipped.
