ice: fix inverted ready check for VF representors

Commit 0f00a897c9fcbd ("ice: check if SF is ready in ethtool ops")
refactored the VF readiness check into a generic repr->ops.ready()
callback but implemented ice_repr_ready_vf() with inverted logic:

  return !ice_check_vf_ready_for_cfg(repr->vf);

ice_check_vf_ready_for_cfg() returns 0 on success, so the negation
makes ready() return non-zero when the VF is ready. All callers treat
non-zero as "not ready, skip", causing ndo_get_stats64, get_drvinfo,
get_strings and get_ethtool_stats to always bail out in switchdev mode.

Remove the erroneous negation. The SF variant ice_repr_ready_sf() is
already correct (returns !active, i.e. non-zero when not active).
