Julien BERAUD f8f2833c88 AP_HAL_Linux: use I2C_SLAVE_FORCE in case of error 
When there is already a driver registered on an i2c bus, the I2C_SLAVE ioctl
returns an error.
When it happens, it is better to display a warning and try to force the address.
It is especially useful on the bebop when killing the regular autopilot that uses
iio drivers to access the imu because else we would need to manually unbind the
driver in an init procedure.

I have added a warning because this error can also be resulting of another cause.
If the error is not EBUSY, then panic

If the I2C_SLAVE_FORCE ioctl fails then we panic because one of the i2c devices
won't be working properly.
