[PATCH 2/3] target/riscv/kvm: initialize 'vlenb' via get-reg-list

KVM will check for the correct 'reg_size' when accessing the vector registers, erroring with EINVAL if we encode the wrong size in reg ID. Vector registers varies in size with the vector length in bytes, or 'vlenb'. This means that we need the current 'vlenb' being used by the host, otherwise we wo
