[PATCH 3/3] soc-knav_dma: Delete error messages for a failed memory allocation in two functions

[elfring@users.sourceforge.net (SF Markus Elfring)]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 1 May 2017 21:14:48 +0200

The script "checkpatch.pl" pointed information out like the following.

WARNING: Possible unnecessary 'out of memory' message

Thus remove such statements here.
