mm/page_alloc.c: remove pageblock_default_order()
commit 955c1cd7401565671b064e499115344ec8067dfd upstream.
This has always been broken: one version takes an unsigned int and the
other version takes no arguments. This bug was hidden because one
version of set_pageblock_order() was a macro which doesn't evaluate its
argument.
Simplify it all and remove pageblock_default_order() altogether.
