Validate user access to vip_subnet_id when creating a LB

Browse Source 
A user was able to create a LB using a vip_subnet_id from another user
(by passing the UUID).
Now, the vip_subnet_id parameter is validated using the user context,
so an error is returned if the subnet doesn't belong to the user.

I479019a911b5a1acfc1951d1cbbc2a351089cb4d was a previous attempt to fix
that bug but vip_subnet_id check was missing.

Fix a bug that allowed a user to create a load balancer on a
``vip_subnet_id`` that belongs to another user using the subnet UUID.
