vaapipostproc: lock ensure_filter with postproc_lock

gst_vaapipostproc_ensure_filter might free the allowed_srcpad_caps
and allowed_sinkpad_caps. This can race with copying these caps in
gst_vaapipostproc_transform_caps and lead to segfaults.

The gst_vaapipostproc_transform_caps function already locks
postproc_lock before copying the caps. Make sure that calls to
gst_vaapipostproc_ensure_filter also acquire this lock.
