[PATCH 2/2] KVM: SVM: Drop unnecessary avic_vm_destroy() call on init failure

[Sean Christopherson <seanjc@google.com>]

Don't bother calling avic_vm_destroy() when allocating the logical ID table
fails, as there is nothing to clean up now that the physical ID table is
allocated later, on-demand at first vCPU creation.

For all intents and purposes, no functional change intended, as calling
avic_vm_destroy() is a big nop in this case.

Fixes: 54ffe74cc4ab ("KVM: SVM: Move AVIC Physical ID table allocation to vcpu_precreate()")
