ALSA: seq: Fix missing bank setup between MIDI1/MIDI2 UMP conversion

Browse source

When a UMP packet is converted between MIDI1 and MIDI2 protocols, the
bank selection may be lost.  The conversion from MIDI1 to MIDI2 needs
the encoding of the bank into UMP_MSG_STATUS_PROGRAM bits, while the
conversion from MIDI2 to MIDI1 needs the extraction from that
instead.

This patch implements the missing bank selection mechanism in those
conversions.
