scsi: Fix scsi_bus_legacy_add_drive() scsi-generic with serial
scsi_bus_legacy_add_drive() creates either a scsi-disk or a
scsi-generic device. It sets property "serial" to argument serial
unless null. Crashes with scsi-generic, because it doesn't have such
the property.
Only usb_msd_initfn_storage() passes non-null serial. Reproducer:
$ qemu-system-x86_64 -nodefaults -display none -S -usb \
-drive if=none,file=/dev/sg1,id=usb-drv0 \
-device usb-storage,id=usb-msd0,drive=usb-drv0,serial=123
qemu-system-x86_64: -device usb-storage,id=usb-msd0,drive=usb-drv0,serial=123: Property '.serial' not found
Aborted (core dumped)
Fix by handling exactly like "removable": set the property only when
it exists.
