Andrew Tridgell 79148498d3 AP_NavEKF2: don't reset EKx_GPS_TYPE when GPS has no vertical velocity 
setting the parameter to 1 causes the following issues:

 - the GPS may not have vertical velocity at the time the parameter
   set happens, but may get it later when the GPS is fully configured

 - we may switch between GPS modules which do/don't have vertical
   velocity

 - the user may download parameters after the set(1), and end up with
   incorrect parameters they may later load onto the vehicle,
   permanently disabling use of vertical velocity

Andrew Tridgell 01cd678244 AP_NavEKF2: fixed memory corruption on push before init 
this fixes a bug that happens with VISION_SPEED_ESTIMATE from a
companion computer, which may come in before the EKF buffers are
allocated. That causes a push to an uninitialised ringbuffer which
triggers memory corruption
