ALSA: line6: Fix racy access to midibuf
There can be concurrent accesses to line6 midibuf from both the URB
completion callback and the rawmidi API access. This could be a cause
of KMSAN warning triggered by syzkaller below (so put as reported-by
here).
This patch protects the midibuf call of the former code path with a
spinlock for avoiding the possible races.
