AP_AHRS: restore DCM attitude before update()
...
The DCM drift correction code uses the current attitude to calculate
error values to update its gyro drift correction. If we were using EKF
then without this patch the DCM code running as an alternative AHRS
source would be using the EKF attitude for calculating the error
value, leading to very bad gyro drift estimation

AHRS: rename ekfNotStarted method to initialised
...
