sparse: add noclone as an ignored attribute

From: Randy Dunlap <[email protected]>

Add attribute "noclone" or "__noclone" or "__noclone__" as an ignored attribute. Fixes this sparse warning:

arch/x86/kvm/vmx.c:6268:13: error: attribute '__noclone__': unknown attribute

The change looks good. Can you add a test case for the noclone attribute in the validations directory? I am happy to apply it.

Also add test case for 'noclone': validation/attr-noclone.c. 'make check' says for this test case:
TEST attribute noclone (attr-noclone.c)

Thanks, applied.
