hw/sparc/sun4m: Fix implicit creation of "-drive if=scsi" devices

The global hack for creating SCSI devices has recently been removed,
but this apparently broke SCSI devices on some boards that were not
ready for this change yet. For the sun4m machines you now get:

$ sparc-softmmu/qemu-system-sparc -boot d -cdrom x.iso
qemu-system-sparc: -cdrom x.iso: machine type does not support if=scsi,bus=0,unit=2

Fix it by calling scsi_bus_legacy_handle_cmdline() after creating the
corresponding SCSI controller.
