PNP: remove extra 0x100 bit from option priority
When building resource options, ISAPNP and PNPBIOS set the priority to something like "0x100 | PNP_RES_PRIORITY_ACCEPTABLE", but we immediately mask off the 0x100 again in pnp_build_option(), so that bit looks superfluous. Thanks to Rene Herman <rene.herman@gmail.com> for pointing this out.
