[3.13-stable] Revert "PCI: Enable INTx in pci_reenable_device() only when MSI/MSI-X not enabled"

This reverts commit 16d36cdf.

... which was applied to 3.13-stable twice, first as:
        bb7048ea
and then again as:
        16d36cdf

This revert relates only to 3.13-stable, and the fix itself remains in 3.13.
