Darshana Padmadas cfb769a843 iio: imu: Use iio_trigger_get for indio_dev->trig assignment 
[ Upstream commit 4ce7ca89d6 ]

This patch uses iio_trigger_get to increment the reference
count of trigger device, to avoid incorrect assignment.
Can result in a null pointer dereference during removal if the
trigger has been changed before removal.

This patch refers to a similar situation encountered through the
following discussion:
