gst/gstpad.c: While checking the flag for reentrancy in the gstcaps function is nice to detect recursive invocations,...

Original commit message from CVS:
* gst/gstpad.c: (gst_pad_get_caps), (gst_pad_peer_get_caps):
While checking the flag for reentrancy in the gstcaps function
is nice to detect recursive invocations, it also makes it
impossible to call getcaps from multiple threads, which must be
possible. So, checking for recursive calls has to go.
