[PATCH] net: aquantia: Fix an error handling path in 'aq_pci_probe()'

The position of 2 labels should be swapped in order to release resources
in the correct order and avoid leaks.

Fixes: 23ee07ad3c2f ("net: aquantia: Cleanup pci functions module")
Signed-off-by: Christophe JAILLET <redacted>

The order of 'pci_release_regions()' and 'free_netdev()' is in reverse
order in the 'aq_pci_remove()' function.
I don't know if done on purpose and/or needed, so I've left it as-is.

Patch timing is sometimes surprising!

Not sure at all if it can be an issue, but I also noted that the order 
of 'pci_release_regions()' and 'free_netdev()' is in reverse
order in the 'aq_pci_remove()' function.

Indeed it.

I think the order is not important here, so believe thats merely a cosmetics.
