KVM: selftests: Get VM's binary stats FD when opening VM
Get and cache a VM's binary stats FD when the VM is opened, as opposed to
waiting until the stats are first used. Opening the stats FD outside of
__vm_get_stat() will allow converting it to a scope-agnostic helper.
Note, this doesn't interfere with kvm_binary_stats_test's testcase that
verifies a stats FD can be used after its own VM's FD is closed, as the
cached FD is also closed during kvm_vm_free().
