This sets all channels to zero, including unused channels. Any consumer of the data using the channel count will not see a difference, but this is helpful to avoid confusion in log analysis.

Because _pins[i] is set from parameter value - 1

   This is the root cause of https://github.com/PX4/Firmware/issues/9461
   The _pins array was initialized to -1. It was used to index the
   _gpios array. The value at _gpios[-1] was a number that mapped to
   Analog mode on Port A pin 0. These is the UART4_TX pin and was
   being reconfigured by the fault in the camera_trigger to an
   alaog input.

   This reverts commit a62a71f4.
   The root cause was the camera trigger passing invalid pin
   configuration setting overwriting the UART4 TX pin setting

analyse_logdata_ekf:
- fix the buffer to start the analyses 5s after takeoff and end
them 5s before landing for logs that start or finish in air
- add flag for turning on-off 5s late start early end buffer
- split the combined imu sensor check into checks for vibration,
bias and output predictor
