Fix the RIL-to-HIDL conversion for Cell Lat and Long

The legacy RIL interface received Lat and Long in that order.
The HIDL interface structure uses Long and Lat. This fixes
a swaparoo in the compatibility layer.

 * RIL_REQUEST_VOICE_REGISTRATION_STATE

 * ... skipping a bunch of stuff

 * ((const char **)response)[5] is Base Station latitude if registered on a
 *                              CDMA system or NULL if not. Base Station
 *                              latitude is a decimal number as specified in
 *                              3GPP2 C.S0005-A v6.0. It is represented in
 *                              units of 0.25 seconds and ranges from -1296000
 *                              to 1296000, both values inclusive (corresponding
 *                              to a range of -90 to +90 degrees).

 *                              longitude is a decimal number as specified in
