proc_lib: Don't call erlang:get_stacktrace/0 twice
proc_lib calls erlang:get_stacktrace/0 twice, which is unnecessary, and potentially unsafe since there are calls to many functions in between. Any of the calls could potentially cause and catch an exception, invalidating the stacktrace. Only call erlang:get_stacktrace/0 once, and pass the result to the second place where it is needed.
