[PATCH v2 17/50] KVM: arm64: Free hypervisor allocations if vector slot init fails

[Sean Christopherson <seanjc@xxxxxxxxxx>]

Teardown hypervisor mode if vector slot setup fails in order to avoid
leaking any allocations done by init_hyp_mode().

Fixes: b881cdce77b4 ("KVM: arm64: Allocate hyp vectors statically")
