ring-buffer: Remove obsolete rb_event_is_commit()
Commit a389d86f7fd0 ("ring-buffer: Have nested events still record running time stamp") removed the only uses of rb_event_is_commit() in rb_update_event() and rb_update_write_stamp(). Hence, since then, make CC=clang W=1 warns: kernel/trace/ring_buffer.c:2763:1: warning: unused function 'rb_event_is_commit' [-Wunused-function] Remove this obsolete function.
