PCI: Fix unaligned access in AF transaction pending test

Browse source

commit d066c946a8 upstream.

pci_wait_for_pending() uses word access, so we shouldn't be passing
an offset that is only byte aligned.  Use the control register offset
instead, shifting the mask to match.

Fixes: d0b4cc4e32 ("PCI: Wrong register used to check pending traffic")
Fixes: 157e876ffe ("PCI: Add pci_wait_for_pending() (refactor pci_wait_for_pending_transaction())
