ALSA: pcm: oss: Handle missing errors in snd_pcm_oss_change_params*()

Browse Source 
commit 6665bb30a6b1a4a853d52557c05482ee50e71391 upstream.

A couple of calls in snd_pcm_oss_change_params_locked() ignore the
possible errors.  Catch those errors and abort the operation for
avoiding further problems.
