[PATCH v2 07/10] drm/{i915, xe}/fbdev: add intel_fbdev_fb_bo_destroy()

[Jani Nikula]

i915 and xe do different things on the failure path; i915 calls
drm_gem_object_put() while xe calls xe_bo_unpin_map_no_vm(). Add a
helper to enable further refactoring.

v2: Call drm_gem_object_put() on intel_fbdev_fb_bo_destroy()
