Takashi Iwai 8c15a18331 ALSA: seq: Avoid confusion of aligned read size 
Currently the read event packet size in snd_seq_read() is defined by
client->midi_version value that is guaranteed to be zero if UMP isn't
enabled.  But the static analyzer doesn't know of the fact, and it
still suspects as if it were leading to a potential overflow.

Add the more explicit check of CONFIG_SND_SEQ_UMP to determine the
aligned_size value for avoiding the confusion.
