4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 1492623e837fe7ca6296f7f5411328307e242771 ]
If an error occurs after the call to 'pci_alloc_irq_vectors()', we must
call 'pci_free_irq_vectors()' in order to avoid a resource leak.
The same sequence is already in place in the corresponding 'cgx_remove()'
function.
Fixes: 1463f382f58d ("octeontx2-af: Add support for CGX link management")
