KVM-async_pf: Delete an unnecessary check before the function call "kmem_cache_destroy"
The kmem_cache_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
