Alexander Sverdlin 88d3426942 MIPS: bootmem: Fix mapstart calculation for contiguous maps ...

Commit a6335fa1 fixed the case with gap between initrd and next usable PFN zone,
but broken the case when initrd is combined with usable memory into one region
(in add_memory_region()). Restore the fixup initially brought in by f9a7febd.
