ALSA: seq: Fix incorrect sanity check at snd_seq_oss_synth_cleanup()
[ Upstream commit 599151336638d57b98d92338aa59c048e3a3e97d ]
ALSA sequencer OSS emulation code has a sanity check for currently
opened devices, but there is a thinko there, eventually it spews
warnings and skips the operation wrongly like:
WARNING: CPU: 1 PID: 7573 at sound/core/seq/oss/seq_oss_synth.c:311
Fix this off-by-one error.
