tools lib traceevent: Add __maybe_unused to unused parameters
Fixing the build on 32-bit Fedora 14:
tools/lib/traceevent/event-parse.c: In function ‘print_event_fields’:
tools/lib/traceevent/event-parse.c:3934:69: error: unused parameter ‘size’
tools/lib/traceevent/event-parse.c: In function ‘pevent_strerror’:
tools/lib/traceevent/event-parse.c:5074:36: error: unused parameter ‘pevent’
