fdc: Fix fallback=auto error handling
fdctrl_realize_common() rejects fallback=auto. Used by devices
"isa-fdc", "sysbus-fdc", "SUNW,fdtwo". The error handling is broken:
$ qemu-system-x86_64 -nodefaults -device isa-fdc,fallback=auto,driveA=fd0 -drive if=none,id=fd0
**
ERROR:/work/armbru/qemu/hw/block/fdc.c:434:pick_drive_type: assertion failed: (drv->drive != FLOPPY_DRIVE_TYPE_AUTO)
Aborted (core dumped)
Cause: fdctrl_realize_common() neglects to bail out after setting the
error. Fix that.
Fixes: a73275dd6f
