memblock: reserve_mem: fix end caclulation in reserve_mem_release_by_name()

free_reserved_area() expects end parameter to point to the first address
after the area, but reserve_mem_release_by_name() passes it the last
address inside the area.

Remove subtraction of one in calculation of the area end.
