[Qemu-devel] [PATCH 3/8] block: bdrv_img_create(): move parameter list printing to qemu-img

[Luiz Capitulino]

Today, bdrv_img_create() prints the parameter list used to create the
new image to stdout, like this:

   Formatting '/tmp/a', fmt=qcow2 size=10737418240 encryption=off 
cluster_size=65536 lazy_refcounts=off

As the transaction QMP command calls bdrv_img_create(), this message
is also printed when using QMP.

This commit moves the printing of the parameter list to qemu-img instead.
This way we avoid printing it in QMP and from whatever bdrv_img_create()
usage we might have in the future.
