Markus Armbruster 07a978ef37 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.
