[PATCH 2/5] um: port: Delete three error messages for a failed memory allocation

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 18 Jan 2017 22:00:14 +0100

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

WARNING: Possible unnecessary 'out of memory' message

Thus fix the affected source code places.
