Albert Esteve a641521e50 hw/virtio/vhost-user: avoid using unitialized errp 
During protocol negotiation, when we the QEMU
stub does not support a backend with F_CONFIG,
it throws a warning and supresses the
VHOST_USER_PROTOCOL_F_CONFIG bit.

However, the warning uses warn_reportf_err macro
and passes an unitialized errp pointer. However,
the macro tries to edit the 'msg' member of the
unitialized Error and segfaults.

Instead, just use warn_report, which prints a
warning message directly to the output.

Fixes: 5653493 ("hw/virtio/vhost-user: don't suppress F_CONFIG when supported")
