iio:imu:mpu6050: Fixed segfault in Invensens MPU driver due to null dereference

Browse source

commit b9b3a41893 upstream.

The driver segfaults when the kernel boots with device tree as the
platform data is then not present and the pointer is deferenced without
checking it is not null.  This patch introduces such a check avoiding the
crash.
