hw/block/fdc: Fix 'fallback' property on sysbus floppy disk controllers
Setting the 'fallback' property corrupts the QOM instance state
(FDCtrlSysBus) because it accesses an incorrect offset (it uses
the offset of the FDCtrlISABus state).
Cc: qemu-stable@nongnu.org
Fixes: a73275dd6fc ("fdc: Add fallback option")
