Takashi Iwai 86496fd4a2 ALSA: seq: Fix snd_seq_expand_var_event() call to user-space
The recent fix to clear the padding bytes at
snd_seq_expand_var_event() broke the read to user-space with
in_kernel=0 parameter.  For user-space address, it has to use
clear_user() instead of memset().

Fixes: f80e6d60d6 ("ALSA: seq: Clear padded bytes at expanding events")
