[PATCH 2/4] tests: extend TEST_NESTED_NLATTR_OBJECT macro

[JingPiao Chen]

Extend TEST_NESTED_NLATTR_OBJECT macro for multi-nested netlink attribute.
Such as:
[MDBA_MDB] = {
	[MDBA_MDB_ENTRY] = {
		[MDBA_MDB_ENTRY_INFO] {
			struct br_mdb_entry
			[MDBA_MDB_EATTR attributes]
		}
	}
}

* tests/test_nlattr.h (TEST_NESTED_NLATTR_OBJECT_EX_,
TEST_NESTED_NLATTR_OBJECT_EX): New macros.
(TEST_NESTED_NLATTR_OBJECT): Use TEST_NESTED_NLATTR_OBJECT_EX_.
