[PATCH v3 4/4] iio: gyro: mpu3050: Fix out-of-sequence free_irq()

[Ethan Tidmore]

The triggered buffer is initialized before the IRQ is requested. The
removal path currently calls  iio_triggered_buffer_cleanup() before 
free_irq(). This violates the expected LIFO. 

Place free_irq() in correct location.
