Subject: [PATCH 4/7] iscsi-target: Make a variable initialisation a bit more
 obvious in iscsi_create_default_params()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 12 Dec 2015 13:44:06 +0100

The variable "pl" was declared and immediately assigned a return value
from a function call in a separate statement.

* Let us express the desired variable initialisation directly.

* Avoid the repetition of the data type specification for the
  involved memory allocation according to the Linux coding
  style convention.
