x86/MSI-X: access MSI-X table only after having enabled MSI-X

As done in Linux by f598282f51 ("PCI: Fix the NIU MSI-X problem in a
better way") and its broken predecessor, make sure we don't access the
MSI-X table without having enabled MSI-X first, using the mask-all flag
instead to prevent interrupts from occurring.
