accel/qaic: Update MAX_ORDER use to be inclusive

MAX_ORDER was redefined so that valid allocations to the page allocator
are in the range of 0..MAX_ORDER, inclusive in the commit
23baf831a32c ("mm, treewide: redefine MAX_ORDER sanely").

We are treating MAX_ORDER as an exclusive value, and thus could be
requesting larger allocations.  Update our use to match the redefinition
of MAX_ORDER.
