[PATCH] lib/test_meminit: fix off-by-one error in test_pages()

[Greg Kroah-Hartman]

In commit efb78fa86e95 ("lib/test_meminit: allocate pages up to order
MAX_ORDER"), the loop for testing pages is set to "<= MAX_ORDER" which
causes crashes in systems when run.  Fix this to "< MAX_ORDER" to fix
the test to work properly.
