Roman Kagan 025faa872b vhost-user: stick to -errno error return convention 
VhostOps methods in user_ops are not very consistent in their error
returns: some return negated errno while others just -1.

Make sure all of them consistently return negated errno.  This also
helps error propagation from the functions being called inside.
Besides, this synchronizes the error return convention with the other
two vhost backends, kernel and vdpa, and will therefore allow for
consistent error propagation in the generic vhost code (in a followup
patch).
