Subject: [PATCH] test/vhost: Fix arithmetic check against $max_disks

The size of the nvmes[] was being compared against a plain string
(which in arithmetic context always evaluates to 0) due to improper
var referencing.

Fix this by using (( )) to be more flexible and not depend on the
parameter expansion syntax.
