[PATCH -next] swiotlb: make io_tlb_overflow static

[FUJITA Tomonori]

We don't need to export io_tlb_overflow_buffer. I'll remove
io_tlb_overflow_buffer completely in the long term though.

This can be applied to:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb-2.6.git

I've stuck it in a new branch (devel/swiotlb-0.9).
