[patch] Fix incoming compression statistics

[Christoph Biedl]

Hello,

somewhere between 6.7 and 7.4, the compression statistics shown when
running the client with -C -v got messed up. For the incoming
compression, the numbers for outgoing are used, reversed.

This got reported in https://bugs.debian.org/797964 but appearently
was never forwarded upstream. Trivial patch below, kudos to Russell Coker.
