Enable/disable radio interface on setup/deactivate

When a RIL request to setup or deactivate data calls the radio interface
would previously be left up. This caused some problems for IPv6 when
switching between WiFi and radio. When WiFi was disable the radio
interface would not send a router solicitation and so the IPv6 router
table would not be populated with a default gateway. Disabling and
enabling the interface solves this since enabling the interface triggers
the router solicitation. Additionally this also makes networking
unavailable when radio data is turned off as one might expect.
