tracing: tprobe-events: Fix to put tracepoint_user when disable the tprobe

Browse source

commit c91afa7610 upstream.

__unregister_trace_fprobe() checks tf->tuser to put it when removing
tprobe. However, disable_trace_fprobe() does not use it and only calls
unregister_fprobe(). Thus it forgets to disable tracepoint_user.

If the trace_fprobe has tuser, put it for unregistering the tracepoint
callbacks when disabling tprobe correctly.
