[PATCH] KVM: selftests: Fix reg_list and VM leak in get_reg_list test

[Tharit Tangkijwanichakul]

Calling the test with --list or --list-filtered causes an early return
in run_test() which skips freeing the reg_list and vm.

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

Tested on a Rock 5B (RK3588). Running the test with --list and
--list-filtered now exercises the goto path added by this fix and exits
cleanly.
