Remove an unneeded goto in the decompressor; it turns out that the state of ip_ after decompression (or attempted decompresion) is completely irrelevant, so we don't need the trailer.

Performance is, as expected, mostly flat -- there's a curious ~3-5%
loss in the "lsp" test, but that test case is so short it is hard to say
anything definitive about why (most likely, it's some sort of
unrelated effect).
