[PATCH] exit early in floppy_init when no floppy exists

modprobe -v floppy on a Apple G5 writes incorrect stuff to dmesg:

Floppy drive(s): fd0 is 2.88M

The reason is that the legacy io check happens very late,
when part of the floppy stuff is already initialized.
check_legacy_ioport() returns either -ENODEV right away, or it walks
the device-tree looking for a floppy node.
