[PATCH kernel] powerpc/powernv/ioda: Finish removing explicit max window size check

9003a2498 removed checn from the DMA window pages allocator, however
the VFIO driver tests limits before doing so by calling
the get_table_size hook which was left behind; this fixes it.

It is properly tested now. Only affected folks for now are DPDK guys
with machines with non-power-of-two physical RAM amount.
