ALSA: seq: Degrade the error message for too many opens

[ Upstream commit da10816e3d923565b470fec78a674baba794ed33 ]

ALSA OSS sequencer spews a kernel error message ("ALSA: seq_oss: too
many applications") when user-space tries to open more than the
limit.  This means that it can easily fill the log buffer.

Since it's merely a normal error, it's safe to suppress it via
pr_debug() instead.
