[PATCH 27/54] md/raid5: Return directly after a failed kzalloc() in setup_conf()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 4 Oct 2016 22:44:59 +0200

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

* Delete a repeated check for the local variable "conf"
  which became unnecessary with this refactoring.
