Extend the management of PCIM_CMD_INTxDIS.

We now explicitly enable INTx during bus_setup_intr() if it is needed.
Several of the ata drivers were managing this bit internally.  This is
better handled in pci and it should work for all drivers now.

We also mask INTx during bus_teardown_intr() by setting this bit.
