For BOs imported from outside of amdgpu, setting of amdgpu_gem_object_funcs
was missing in amdgpu_dma_buf_create_obj. Fix by refactoring BO creation
and amdgpu_gem_object_funcs setting into single function called
from both code paths.

Fixes: d693def4fd1c ("drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver")

v2: Use use amdgpu_gem_object_create() directly
v3: fix warning
