[PATCH 2/2] perf tools: Remove warnings on JIT samples for srcline sort key

[Namhyung Kim <namhyung@kernel.org>]

From: Namhyung Kim <namhyung.kim@lge.com>

When using the srcline sort key with perf report, I see many lines of
warning related to JIT samples like below:

  addr2line: '/tmp/perf-1397.map': No such file

Since it's not a ELF binary and doesn't provide such information, just
use the raw ip address.

Maybe you want fold this into patch #1 and I'm okay with it. :)
