seq: Add snd_seq_ump_ev_clear()

Like snd_seq_ev_clear(), let's add a helper to clear the event record for a UMP-capable sequencer event. While we're at it, change snd_seq_ev_clear() to be a static inline function, so that we make sure that the proper pointer type is passed. Signed-off-by: Takashi Iwai <[email protected]>
