    z80/disassembler: call memory_error_func when appropriate
    
    If a call to the read_memory_func fails then we should call the
    memory_error_func to notify the user of the disassembler of the
    address that was a problem.
    
    Without this GDB will report all memory errors as being at address
    0x0.
    
    opcodes/ChangeLog:
    
            * z80-dis.c (fetch_data): Call memory_error_func if the
            read_memory_func call fails.
