Greg Kroah-Hartman b930f0f7bb lib/test_meminit: fix off-by-one error in test_pages() ...

commit efb78fa86e ("lib/test_meminit: allocate pages up to order
MAX_ORDER") works great in kernels 6.4 and newer thanks to commit
23baf831a3 ("mm, treewide: redefine MAX_ORDER sanely"), but for older
kernels, the loop is off by one, which causes crashes when the test
runs.

Fix this up by changing "<= MAX_ORDER" "< MAX_ORDER" to allow the test
to work properly for older kernel branches.
