ALSA: ump: Correct wrong byte size at converting a UMP System message 

A wrong size for UMP_SYSTEM_STATUS_MIDI_TIME_CODE and case
UMP_SYSTEM_STATUS_SONG_SELECT was reported at converting to the legacy
MIDI 1.0 stream.  This patch corrects the value.

Fixes: 0b5288f5 ("ALSA: ump: Add legacy raw MIDI support")
