tracing: Move a printk out of ftrace_raw_reg_event_foo()
Move the printk from each ftrace_raw_reg_event_foo() to
its caller ftrace_event_enable_disable(). This avoids each
regfunc trace event callbacks to handle a same error report
that can be carried from the caller.
See how much space this saves:

window of pid to comm resolution]
