Fix range check in H5_addr_overlap (#4278)

Browse Source 
When the H5_addr_overlap macro was updated to use H5_RANGE_OVERLAP,
it failed to take into account that H5_RANGE_OVERLAP expects the
range to be inclusive. This lead to an assertion failure in
H5MM_memcpy due to a memcpy operation on overlapping memory.
This has been fixed by subtracting 1 from the calculated high
bound values passed to H5_RANGE_OVERLAP
