drm/vmwgfx: Fix depth input into drm_mode_legacy_fb_format
Currently the pitch is passed in as depth. This causes drm_mode_legacy_fb_format() to return the wrong pixel format. The wrong pixel format will be rejected by vmw_kms_new_framebuffer(), thus leaving par->set_fb to NULL. This eventually causes a crash in vmw_fb_setcolreg() when the code tries to dereference par->set_fb.
