bdrv_open_driver() is called in two places, bdrv_new_open_driver() and
bdrv_open_common(). In the latter, failure cleanup in is in its caller,
bdrv_open_inherit(), which unrefs the bs->file of the failed driver open
if it exists.
Let's move the bs->file cleanup to bdrv_open_driver() to take care of
all callers and do not set bs->drv to NULL unless the driver's open
function failed. When bs is destroyed by removing its last reference, it
calls bdrv_close() which checks bs->drv to perform the needed cleanups
and also call the driver's close function. Since it cleans up options
and opaque we must take care not leave dangling pointers.
The error paths in bdrv_open_driver() are now two:
If open fails, drv->bdrv_close() should not be called. Unref the child
if it exists, free what we allocated and set bs->drv to NULL. Return the
error and let callers free their stuff.
If open succeeds but we fail after, return the error and let callers
unref and delete their bs, while cleaning up their allocations.

On one hand, the _make_test_img invocation for creating the target image
was missing a -u because its backing file is not supposed to exist at
that point.
On the other hand, nobody noticed probably because the backing file is
created later on and _cleanup failed to remove it: The quotation marks
were misplaced so bash tried to delete a file literally called
"$TEST_IMG{,.target}..." instead of performing brace expansion. Thus, the
files stayed around after the first run and qemu-img create did not
complain about a missing backing file on any run but the first.

When the PMSAv7 implementation was originally added it was for R profile
CPUs only, and reset was handled using the cpreg .resetfn hooks.
Unfortunately for M profile cores this doesn't work, because they do
not register any cpregs. Move the reset handling into arm_cpu_reset(),
where it will work for both R profile and M profile cores.
