tracing: Fix anonymous unions in struct ftrace_event_call

Browse Source 
gcc <= 4.5.x has significant limitations with respect to initialization
of anonymous unions within structures. They need to be surrounded by
brackets, _and_ they need to be initialized in the same order in which
they appear in the structure declaration.
