iio: gyro: mpu3050: Fix error handling in mpu3050_trigger_handler
commit 6dbbbe4cfd398704b72b21c1d4a5d3807e909d60 upstream.
There is one regmap_bulk_read() call in mpu3050_trigger_handler
that we have caught its return value bug lack further handling.
Check and terminate the execution flow just like the other three
regmap_bulk_read() calls in this function.
