gst/: Fix refcounting in utils function.

Browse source 
Original commit message from CVS:
* gst/gstelement.c: (gst_element_add_pad), (gst_element_query):
* gst/gstutils.c: (gst_element_get_compatible_pad_template),
(gst_element_link_pads), (gst_element_query_position),
(gst_element_query_convert), (intersect_caps_func),
(gst_pad_query_position), (gst_pad_query_convert):
Fix refcounting in utils function.
No point in trying to activate a pad when it's added, it could
be added from the state change function and then we deadlock, the
element has to decide what to do.
