[PATCH 2/3] uio: Return directly after a failed kzalloc() in uio_dmem_genirq_probe()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 6 Dec 2017 19:11:49 +0100

* Return directly after a call of the function "kzalloc" failed
  in an if branch.

* Delete the jump label "bad2" which became unnecessary with
  this refactoring.
