[PATCH 13/17] tracing/uprobes: Pass 'is_return' to traceprobe_parse_probe_arg()

[Namhyung Kim <namhyung@kernel.org>]

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

Currently uprobes don't pass is_return to the argument parser so that
it cannot make use of "$retval" fetch method since it only works for
return probes.
