tracing: Add TRACE_ITER_PRINTK flag check in __trace_puts/__trace_bputs
commit f0160a5a2912267c02cfe692eac955c360de5fdf upstream.
The TRACE_ITER_PRINTK check in __trace_puts/__trace_bputs is missing,
so add it, to be consistent with __trace_printk/__trace_bprintk.
Those functions are all called by the same function: trace_printk().
