    PR25344, z80 disassembler recursion

        PR 25344
        * z80-dis.c (suffix): Don't use a local struct buffer copy.
        Peek at next byte to prevent recursion on repeated prefix bytes.
        Ensure uninitialised "mybuf" is not accessed.
        (print_insn_z80): Don't zero n_fetch and n_used here,..
        (print_insn_z80_buf): ..do it here instead.
