We always initialize the type in pnp_init_resources(), and while we
do fiddle with some of the other bits in the flags element, I can't
see anyplace where we would clear the type.

But I did add code to set the type in pnp_clean_resource_table(),
just in case. It could be hard to debug a problem there, and it's
harmless to set it again.
