[PATCH 2/2] tty: moxa: Return directly after a failed kcalloc() in moxa_init_board()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 10 Dec 2017 16:15:41 +0100

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

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