[PATCH i-g-t] tests/sriov_basic: Restore the igt_sriov_is_pf check

[Marcin Bernatowicz]

The requirement `igt_sriov_is_pf` is essential for accurately skipping
tests in scenarios where the `sriov_totalvfs` attribute is absent. This
update restores the previously removed check to ensure proper test
behavior under such conditions.
