[PATCH] ALSA: pcm: Simplify success check in snd_pcm_open_file()

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

snd_pcm_open_file() returns zero on success and a negative error code
on failure. Use !err to check for a successful return instead of
checking for a non-negative value.
