Marek Marczykowski-Górecki 69086bd698 xen-pciback: fix INTERRUPT_TYPE_* defines ...

xen_pcibk_get_interrupt_type() assumes INTERRUPT_TYPE_NONE being 0
(initialize ret to 0 and return as INTERRUPT_TYPE_NONE).
Fix the definition to make INTERRUPT_TYPE_NONE really 0, and also shift
other values to not leave holes.
But also, do not assume INTERRUPT_TYPE_NONE being 0 anymore to avoid
similar confusions in the future.

Fixes: 476878e4b2 ("xen-pciback: optionally allow interrupt enable flag writes")
