[PATCH] drm/prime: Fix documentation of drm_gem_prime_fd_to_handle()

From: Petr Tesarik <petr.tesarik.ext at huawei.com>

The DRM device passed to drm_gem_prime_fd_to_handle() is where the
dma-buf is being imported, not the device where it was exported.

Also fix a trivial typo in drm_gem_prime_import_dev().
