ia64: mmap: Consider pgoff when searching for free mapping



IA64 is the only architecture which does not consider the pgoff value when
searching for a possible free memory region with vm_unmapped_area().
Adding this seems to have no negative side effect on IA64, so add it now
to make IA64 consistent with all other architectures.
