ALSA: seq: Use bool for snd_seq_queue internal flags
commit 4ebd47037027c4beae99680bff3b20fdee5d7c1e upstream.
The snd_seq_queue struct contains various flags in the bit fields.
Those are categorized to two different use cases, both of which are
protected by different spinlocks. That implies that there are still
potential risks of the bad operations for bit fields by concurrent
accesses.
For addressing the problem, this patch rearranges those flags to be
a standard bool instead of a bit field.
