PCI: Fix unaligned access in AF transaction pending test
commit d066c946a866268c14a120b33e7226e899981998 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: d0b4cc4e3270 ("PCI: Wrong register used to check pending traffic")
Fixes: 157e876ffe0b ("PCI: Add pci_wait_for_pending() (refactor pci_wait_for_pending_transaction())
