KVM: arm64: Remove redundant hyp vectors entry
The hyp vectors entry corresponding to HYP_VECTOR_DIRECT (i.e. when neither Spectre-v2 nor Spectre-v3a are present) is unused, as we can simply dispatch straight to __kvm_hyp_vector in this case. Remove the redundant vector, and massage the logic for resolving a slot to a vectors entry.
