floppy: Correct documentation of driver options when used as a module.

The options have to be passed space-separated and prefixed by "floppy=",
rather than separately and unprefixed.

This fixes <http://bugs.debian.org/726655>.

 ============================
 
  If you use the floppy driver as a module, use the following syntax:
-modprobe floppy <options>
+modprobe floppy floppy="<options>"
 
 Example:
- modprobe floppy omnibook messages
+ modprobe floppy floppy="omnibook messages"
 
  If you need certain options enabled every time you load the floppy driver,
 you can put:
 
- options floppy omnibook messages
+ options floppy floppy="omnibook messages"
 
 in a configuration file in /etc/modprobe.d/.
