[PATCH 4/7] cfag12864b: Return directly after a failed get_zeroed_page()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sat, 10 Sep 2016 15:30:56 +0200

* Return directly after a call of the function "get_zeroed_page" failed
  at the beginning.

* Delete the jump label "none" which became unnecessary with
  this refactoring.
