[PATCH i-g-t] tests/sriov_basic: Skip tests if sriov_totalvfs is zero

[Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com>]

There is no point to run the tests if no VFs can be enabled.
Additionally, the `for_random_sriov_num_vfs` macro will lead
to undefined behavior if `sriov_totalvfs` is zero.
