[PATCH 092/161] perf annotate: Reuse path from the result of addr2line

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@xxxxxxx>

In the symbol__get_source_line(), path and src_line->path will have same
value, but they were allocated separately, and leaks one.  Just share
path to src_line->path.
