Subject: [PATCH 08/15] IB/qib: Use PCI_IRQ_MSI_TYPES where appropriate

Seeing as there is shorthand available to use when asking for any type
of interrupt, or any type of message signalled interrupt, leverage it.

Internally I have proposed at last this:

convert the following
if (dd->flags & QIB_HAS_INTX)
flags |= PCI_IRQ_LEGACY;

to
if (dd->flags & QIB_HAS_INTX)
flags = PCI_IRQ_ALL_TYPES;
if (dd->flags & QIB_HAS_INTX)
flags = PCI_IRQ_MSI_TYPES;

This line should be 'else'.
