From: Anirudh Venkataramanan <anirudh.venkataramanan@xxxxxxxxx>
[ Upstream commit c7f2c42b80ed6009f44e355aefc1e40db9485a9d ]
1) When ice_ena_msix_range() fails to reserve vectors, a devm_kfree()
warning was seen in the error flow path. So check pf->irq_tracker
before use in ice_clear_interrupt_scheme().
2) In ice_vsi_cfg(), check vsi->netdev before use.
3) In ice_get_link_status, check link_up before use.
