tracing: Fix wrong usage of strstrip in trace_ksyms
strstrip returns a pointer to the first non space character, but the
code in parse_ksym_trace_str() ignores that.
strstrip is now must_check and therefor we get the correct warning:
kernel/trace/trace_ksym.c:294: warning:
ignoring return value of ‘strstrip’, declared with attribute warn_unused_result
We are really not interested in leading whitespace here.
Fix that and cleanup the dozen kfree() exit pathes.
