pnp: avoid a small unlikely memory leak in proc_read_escd()
There's a small and unlikely memory leak in
drivers/pnp/pnpbios/proc.c::proc_read_escd(). It's inside a sanity check,
so it probably won't trigger often (if at all), however it *is* a potential
leak and it's easy to avoid, so let's just fix it :)
