rtla: Avoid record NULL pointer dereference
Fix the following null/derefnull.cocci errors: ./tools/tracing/rtla/src/osnoisehist.c:870:31-36: ERROR: record is NULL but dereferenced. ./tools/tracing/rtla/src/osnoisetop.c:650:31-36: ERROR: record is NULL but dereferenced. ./tools/tracing/rtla/src/timerlathist.c:905:31-36: ERROR: record is NULL but dereferenced. ./tools/tracing/rtla/src/timerlat_top.c:700:31-36: ERROR: record is NULL but dereferenced.
"record" is NULL before calling osnoiseinittracetool. Add a tag "outfree" to avoid dereferring a NULL pointer.
