tracing: Add TRACE_ITER_PRINTK flag check in __trace_puts/__trace_bputs 

commit f0160a5a29 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().
