xen/pt: split out calculation of throughable mask in PCI config space handling
This is just to avoid having to adjust that calculation later in
multiple places.
Note that including ->ro_mask in get_throughable_mask()'s calculation
is only an apparent (i.e. benign) behavioral change: For r/o fields it
doesn't matter > whether they get passed through - either the same flag
is also set in emu_mask (then there's no change at all) or the field is
r/o in hardware (and hence a write won't change it anyway).
This is a preparatory patch for XSA-131.
