[PATCH 3/4] virtio_blk: Delete an unnecessary initialisation in init_vq()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 13 Sep 2016 13:43:50 +0200

The local variable "err" will be set to an appropriate value
by a following statement.
Thus omit the explicit initialisation at the beginning.
