    opcodes/riscv-dis.c: Remove last_map_state
    
    Before changing the core disassembler, we take care of minor code clarity
    issues and improve readability.
    
    This commit removes unused variable last_map_state (set by the
    print_insn_riscv function but not read anywhere else).
    
    opcodes/ChangeLog:
    
            * riscv-dis.c (last_map_state): Remove.
            (print_insn_riscv): Remove setting last_map_state.
