[PATCH] drm: missing idr_preload_end in drm_gem_flink_ioctl

[Artem Savkov]

Added missing idr_preload_end calls in drm_gem_flink_ioctl().
Without those preemption stays disabled resulting in lots of "scheduling while
atomic" BUGs.

Introduced in 4e486fae707d9a79c76f1be6dcacffc4a721cc1b (linux-next.git)
