target/hppa: Restore unwind_breg before calculating ior

Browse source 
When calculating the IOR for the exception handlers, the current
unwind_breg value is needed on 64-bit hppa machines.
Restore that value by calling cpu_restore_state() earlier, which in turn
calls hppa_restore_state_to_opc() which restores the unwind_breg for the
current instruction.
