lib/test_meminit: allocate pages up to order MAX_ORDER
test_pages() tests the page allocator by calling alloc_pages() with
different orders up to order 10.
However, different architectures and platforms support different maximum
contiguous allocation sizes. The default maximum allocation order
(MAX_ORDER) is 10, but architectures can use CONFIG_ARCH_FORCE_MAX_ORDER
to override this. On platforms where this is less than 10, test_meminit()
will blow up with a WARN(). This is expected, so let's not do that.
Replace the hardcoded "10" with the MAX_ORDER macro so that we test
allocations up to the expected platform limit.
