vmwgfx: Use a mutex to protect gui positioning in vmw_display_unit
To avoid race condition between update_layout ioctl and modeset ioctl
for access to gui_x/y positioning added a new mutex
requested_layout_mutex.
Also used drm_for_each_connector_iter to iterate over connector list.
v2: Tested with CONFIG_PROVE_LOCKING enabled.
