PNP: make pnp_{port,mem,etc}_start(), et al work for invalid resources
Some callers use pnp_port_start() and similar functions without making sure the resource is valid. This patch makes us fall back to returning the initial values if the resource is not valid or not even present. This mostly preserves the previous behavior, where we would just return the initial values set by pnp_init_resource_table(). The original 2.6.25 code didn't range-check the "bar", so it would return garbage if the bar exceeded the table size. This code returns sensible values instead.
