[PULL 08/16] tests/avocado: Remove the non-working virtio_check_params test

[Michael Tokarev]

From: Thomas Huth <thuth@redhat.com>

The test has been marked as broken more than 4 years ago [*],
and so far nobody ever cared to fix it. Thus let's simply remove
it now ... if somebody ever needs it again, they can restore the
file from an older version of QEMU.
