tracing: fix trace_find_cmdline()
Impact: prevent stale command line output
In case there is no valid command line mapping for a pid
trace_find_cmdline() returns without updating the comm buffer. The
trace dump keeps the previous entry which results in confusing trace
output:
<idle>-0 [000] 280.702056 ....
<idle>-23456 [000] 280.702080 ....
Update the comm buffer with "<...>" when no mapping is found.
