qcacmn: Remove serialization vdev destroy handler

Each cmd in serialization list holds a vdev ref by
I8d573ff5a25e6dff928b2708e51ad7b97e292277. When vdev is
destroyed physically, it means vdev ref count is 0, all
serialization cmds of this vdev are released, don't need purge
in vdev destroy handler.

CRs-Fixed: 2367242
