Fix disassembler memory accesses 

Sparc disassembler wants to check previous addresses for some stuff
and this may actually cause faults to be generated to the guest if the
address is close to page start, because of the function used for the
memory access.

Fix by changing ldub_code to cpu_memory_rw_debug, which doesn't trigger
exceptions.
