drm/vmwgfx: Fixes to vmwgfx_fb
[ Upstream commit aa74f0687cfe998e59b20d6454f45e8aa4403c45 ]
1. When unsetting a mode, num_connector should be set to zero
2. The pixel_format field needs to be initialized as newer DRM internal
functions checks this field
3. Take the drm_modeset_lock_all() because vmw_fb_kms_detach() can
change current mode
