qcacmn: Allow nan data interface delete with peers attached

Service layer was not allowed to delete NDI if there are active
NDP sessions (peers). Service layer is expected to delete the
active NDP sessions before issuing NDI delete. However, that
is not guaranteed to happen. Hence allowing internal cleanup
to happen by allowing the command to firmware.
