perf: Fix parsing of __print_flags() in TP_printk()
commit 49908a1b25d448d68fd26faca260e1850201575f upstream. A update is made to the sched:sched_switch event that adds some logic to the first parameter of the __print_flags() that shows the state of tasks. This change cause perf to fail parsing the flags. A simple fix is needed to have the parser be able to process ops within the argument.
