Andrew Tridgell 8a2f1fdb3d AP_Airspeed: fixed airspeed filtering issue
this fixes an issue where an airspeed sensor that becomes unhealthy
can have an undue effect after the sensor becomes healthy again.

In a recent flight log the MS4525 airspeed sensor went unhealthy for a
few seconds, and at the same time gave a reading of 12m/s. The plane
was flying at 24m/s. While the sensor was unhealthy the code correctly
switched to the airspeed estimate, which was fine.

When the airspeed sensor become healthy again the IIR filter in
AP_Airspeed meant that the speed read at 12m/s initially, then came up
to 24m/s over a couple of seconds. This caused the VTOL motors to come
on for a few seconds.
