vfio: Avoid disabling and enabling vectors repeatedly in VFIO migration
In VFIO migration resume phase and some guest startups, there are
already unmasked vectors in the vector table when calling

and enabling vectors repeatedly, let's allocate all needed vectors
first and then enable these unmasked vectors one by one without
disabling.
