ALSA: seq: Fix incorrect UMP type for system messages 

commit edb3277619 upstream.

When converting a legacy system message to a UMP packet, it forgot to
modify the UMP type field but keeping the default type (either type 2
or 4).  Correct to the right type for system messages.

Fixes: e9e02819a9 ("ALSA: seq: Automatic conversion of UMP events")
