[PATCH v2 11/13] hw/ide/atapi: Use qemu_hexdump_line() to avoid sprintf()

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

sprintf() is deprecated on Darwin since macOS 13.0 / XCode 14.1,
resulting in painful developper experience.

Use qemu_hexdump_line() to avoid sprintf() calls, silencing:

  [1367/1604] Compiling C object libcommon.fa.p/backends_tpm_tpm_util.c.o
  backends/tpm/tpm_util.c:355:18: warning: 'sprintf' is deprecated:
    This function is provided for compatibility reasons only.
    Due to security concerns inherent in the design of sprintf(3),
    it is highly recommended that you use snprintf(3) instead.
    [-Wdeprecated-declarations]
            p += sprintf(p, "\n");
                 ^
