oss mixer: Improve error message.

If /dev/mixer does not exist, para_fade fails with

	main: No such file or directory

This is a rather bad error message, since the name of the missing file
is not mentioned. This patch makes oss_mix.c print the additional line

	 oss_mix_open: could not open /dev/mixer
