[ndctl PATCH 2/2] ndctl/test: fix align.sh to not expect initialized labels

[Vishal Verma <vishal.l.verma@intel.com>]

A fresh qemu based system may not have its labels initialized. In this
case, align.sh would get skipped because the label-less namespaces would
be using all available region capacity.

Fix this by initializing labels if a usable region is not found the
first time around, and try again.
