[PATCH] PCI/TPH: Restore TPH Requester Enable correctly

[Robin Murphy]

When we reenable TPH after changing a Steering Tag value, we need the
actual TPH Requester Enable value, not the ST Mode (which only happens
to work out by chance for non-extended TPH in interrupt vector mode).

Fixes: d2e8a34876ce ("PCI/TPH: Add Steering Tag support")
