[PATCH] ALSA: core: Drop redundant stream_open() return check

[phucduc.bui@gmail.com]

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

The previous conversion from nonseekable_open() to stream_open() retained
the existing error check.
Since stream_open() always returns 0, remove the dead error handling path.
