gst/autoplug/gstspider.c (gst_spider_request_new_pad): Fix typo in debug message.

Original commit message from CVS:
* gst/autoplug/gstspider.c (gst_spider_request_new_pad): Fix typo
in debug message.
(gst_spider_create_and_plug): Improve debug message.
General: Replace while loops which iterates over GLists with for
loops. Which are much cleaner, improves readability, especially
for gst_spider_identity_plug
