[PATCH 02/19] perf annotate: Show invalid jump offset in error message

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

To help in debugging when the wrong offset is being used, like in:

       │13d98: ↓ jne    13dd1 <lzma_lzma_preset@@XZ_5.0+0x28e1>

That is the full line from objdump, and it seems what should be used is
13dd1, not 28e1.
