File descriptor vdpa_device_fd is not free in the case of returning
error from vhost_vdpa_get_features. Fixing it by making all errors go to
the same error path.
Resolves: Coverity CID 1490785
Fixes: 8170ab3f43 ("vdpa: Extract get features part from
vhost_vdpa_get_max_queue_pairs")

This patch does not belong in this series. It's not a patch to the
kernel. This is a kernel series.
It would be much more appropriate to put a link to a separately posted
manpage patch in the cover letter.

When resuming after a migration, the backend sends CMD_INIT to the
emulator from the startup callback, then it sends the migration state
from the vmstate to the emulator, then it sends CMD_INIT again. Skip the
first CMD_INIT during a migration to avoid initializing the TPM twice.

When debugging failures in CI which can't be replicated locally it can
be useful to dump a backtrace. However ad-hoc debug code is likely to
fail to compile on numerous hosts so lets package up a utility
function with proper compiler detection.

Not a huge deal, but probably makes mainainers lives a little easier.
Add a change to make Coverity happy.

I've been debugging a segfault in the raspi3b display device, and I've
tracked it down to a race condition, but I'm not sure what the right
way to fix it is...
The race is that a vCPU thread is handling a guest register write that
says "resize the framebuffer", which it implements by calling
qemu_
