ALSA: usb-audio: Cancel pending work at closing a MIDI substream
commit 0125de38122f0f66bf61336158d12a1aabfe6425 upstream.
At closing a USB MIDI output substream, there might be still a pending
work, which would eventually access the rawmidi runtime object that is
being released. For fixing the race, make sure to cancel the pending
work at closing.
