Subject: PCI/AER: Specify the type of Port that was reset
Git-commit: 33ac78bd3b509d36e7f109a447e28af42e637cb2
Patch-mainline: v5.12-rc1
References: bsc#1174426

The AER driver may be called upon to reset either a Downstream or a Root
Port. Check which type it is to properly identify it when logging that
the reset occurred.
