ftrace: Correct a text align for event format output

If we cat debugfs/tracing/events/ftrace/bprint/format, we'll see:
name: bprint
ID: 6
format:
	field:unsigned char common_type;	offset:0;	size:1;
	field:unsigned char common_flags;	offset:1;	size:1;
	field:unsigned char common_preempt_count;	offset:2;	size:1;
	field:int common_pid;	offset:4;	size:4;
	field:int common_tgid;	offset:8;	size:4;

	field:unsigned long ip;	offset:12;	size:4;
	field:char * fmt;	offset:16;	size:4;
	field: char buf;	offset:20;	size:0;

print fmt: "%08lx (%d) fmt:%p %s"

There is an inconsistent blank before char buf.
