O-Subject: [RHEL7 qemu-kvm PATCH 24/26] block: qemu-iotests for vhdx, add write test support
Bugzilla: 879234

This removes the IMGFMT_GENERIC blocker for read-only, so existing
iotests run read/write tests for vhdx images created by qemu-img (e.g.
tests 001, 002, 003).

In addition, this updates the sample image test for the Hyper-V
created image, to verify we can write it as well.

(cherry picked from commit 751aec24cdcd4359b5927df5cebfe6b8d3e74515)

RHEL7 Note:  Difference from upstream - there was a typo in this patch,
             that used 'MM' instead of 'M' for size passed into qemu-io.
             Upstream apparently gobbles the extra 'M' without error,
             but RHEL7 does not.  Fix this so that test 064 passes.
