Patch-mainline: v5.7-rc1
Subject: PCI: hv: Add missing kfree(hbus) in hv_pci_probe()'s error handling path
Git-commit: 42c3d41832ef4fcf60aaa6f748de01ad99572adf
References: jsc#sle-12891

Now that we use kzalloc() to allocate the hbus buffer, we must call
kfree() in the error path as well to prevent memory leakage.

Fixes: 877b911a5ba0 ("PCI: hv: Avoid a kmemleak false positive caused by the hbus buffer")
