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().

Hi Simon,

so how about taking this one? I can't see it in git yet (but maybe I'm looking at the wrong branch).

Pushed to drm-misc-next, thanks!
