Subject: [PATCH 2/3] RDMA/iwpm: Adjust a variable initialisation in
 iwpm_create_nlmsg()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 27 Jan 2018 21:56:54 +0100

The local variable "skb" will be reassigned by a following statement.
Thus adjust the initialisation at the beginning.
