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

From: Namhyung Kim <namhyung.kim@....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.
