rtems_cache_invalidate_multiple_instruction_lines

According with comment in
rtems_cache_invalidate_multiple_instruction_lines(), final_address
indicates the last address which needs to be invalidated. But if in
while loop we got final_address == i_addr condition then loop breaks and
final_address will not be invalidated.
