When the max_addr parameter of efi_find_free_memory() is within bounds of an existing map and fits the reservation, we just return that address as allocation value. That breaks however if max_addr is not page aligned. So ensure that it always comes to us page aligned, simplifying the allocation logic. Without this, I've seen breakage where we were allocating pages at -1U (32bit) which fits into a region that spans beyond 0x100000000. In that case, we would return 0xffffffff as a valid memory allocation, although we usually do guarantee they are all page aligned. Fix this by aligning the max address argument always.
