[PATCH][5/5][resend] floppy.c: Fix device_create_file() warning

[Jesper Juhl]

    This fixes the warning
      warning: ignoring return value of `device_create_file', declared with attribute warn_unused_result in function `floppy_init'.
    It does this by checking the return value and printing a warning message in case of no success.
