ut/vhost: fix vhost_dev_register() tests

Browse Source 
All vhost_dev_register() tests are negative
- they all expect error. They all were failing
on a single check:

*ERROR*: no cpu is selected among reactor mask(=1)
*ERROR*: cpumask 0x1 is invalid (app mask is 0x1)

That's because we mock cpumask parsing. Even when
"parsed", the real cpumask would always be == 0.
Our unit tests were treating this as a valid
behavior. To really test what they should, we
have to properly implement cpumask parsing. That's
what this patch does.

We should also assert against a specific error
code, not just != 0. But that's a matter for
a separate commit.
