[PATCH 3/3] block-aoe: Add spaces for better code readability

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

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 8 May 2017 09:35:25 +0200

The script "checkpatch.pl" pointed information out like the following.

CHECK: spaces preferred around that '-' (ctx:VxV)

Thus fix the affected source code place.
