ALSA: hda: Delete an unnecessary check before the function call “snd_info_free_entry” 

Author: Markus Elfring <elfring@users.sourceforge.net>

The snd_info_free_entry() function tests whether its argument is NULL and
then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
