perf tools: Free 'printk' string in parse_ftrace_printk()
parse_ftrace_printk() tokenizes and parses a line, calling strdup() each
iteration. Add code to free this temporary format string duplicate.
Fixes the following coverity complaints:
Error: RESOURCE_LEAK (CWE-772):
tools/perf/util/trace-event-parse.c:158: overwrite_var: Overwriting
"printk" in "printk = strdup(fmt + 1)" leaks the storage that "printk"
points to.
tools/perf/util/trace-event-parse.c:162: leaked_storage: Variable
"printk" going out of scope leaks the storage it points to.
