[PATCH] KVM: selftests: Fix VM leak in early return

[Tharit Tangkijwanichakul]

test_mmio_ease() returns early and skips the call to kvm_vm_free() when
ID_AA64PFR1_EL1 is not available.

Use a goto so that the early return joins the common exit path.

Tested on a Rock 5B (RK3588). ID_AA64PFR1_EL1.DF2 is not implemented,
so test_mmio_ease() takes the skip path exercised by this fix.
