Don't bother rebasing onto linux-pci/next.

If your patches actually *depend* on something that has already been
merged onto a PCI topic branch, you should mention that and say which
branch.

But otherwise, it's easiest if they are based on linux-pci/master,
because that's how Lorenzo and I apply them.

linux-pci/next is ephemeral and I frequently rebuild it to fix errors,
add acks, etc.

It doesn't *hurt* that you rebased, but it doesn't help anything
either, and it's a little needless work for you.
