    ALSA: seq: Don't clear bank selection at event -> UMP MIDI2 conversion
    
    [ Upstream commit a200df7deb3186cd7b55abb77ab96dfefb8a4f09 ]
    
    The current code to convert from a legacy sequencer event to UMP MIDI2
    clears the bank selection at each time the program change is
    submitted.  This is confusing and may lead to incorrect bank values
    tranmitted to the destination in the end.
    
    Drop the line to clear the bank info and keep the provided values.
