    sound: Fix SEQ_SYSEX() macro
    
    Correct implementation also found in Linux's soundcard.h:
    https://github.com/torvalds/linux/blob/master/include/uapi/linux/soundcard.h#L1178
    
    seq_processevent() interprets event[1] as device number and does not
    work properly with current SEQ_SYSEX() implementation.
    
    Note: soundcard.h has its own funky style, which this commit follows
