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

[Jesper Juhl <jesper.juhl@gmail.com>]

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.
