I don't like when we change a function like this but it still compiles fine.
If someone is working on a driver and hasn't pushed it yet, then it's probably
supposed to be using the new pcim_intx() but they won't discover that until they
detect the leaks at runtime.

Why not leave the pci_intx_unmanaged() name.  It's ugly and that will discorage
people from introducing new uses.
