Subject: [PATCH 5.17 173/298] stmmac: intel: Fix an error handling path in intel_eth_pci_probe()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 5e74a4b3ec1816e3bbfd715d46ae29d2508079cb ]

When the managed API is used, there is no need to explicitly call
pci_free_irq_vectors().

This looks to be a left-over from the commit in the Fixes tag. Only the
.remove() function had been updated.

So remove this unused function call and update goto label accordingly.

Fixes: 8accc467758e ("stmmac: intel: use managed PCI function on probe and resume")
