vhost-user: fix shared object return values

VHOST_USER_BACKEND_SHARED_OBJECT_ADD and
VHOST_USER_BACKEND_SHARED_OBJECT_REMOVE state
in the spec that they return 0 for successful
operations, non-zero otherwise. However,
implementation relies on the return types
of the virtio-dmabuf library, with opposite
semantics (true if everything is correct,
false otherwise). Therefore, current
implementation violates the specification.

Revert the logic so that the implementation
of the vhost-user handling methods matches
the specification.
