Correct wrong test and update of arm thumb offset information.

* lib/jit_arm-cpu.c, lib/jit_arm.c: Correct wrong test and update of the thumb offset information, when checking if needing to patch a jump from arm to thumb mode. The problem would happen when remapping the code buffer, and the new address being lower than the previous one.
