gdpdepay: don't allocation query if caps aren't fixed

When querying downstream for allocation, and the source caps hasn't
set its caps, using ANY by default, it raises a critical message in
console:

CRITICAL **: gst_video_info_from_caps: assertion 'gst_caps_is_fixed (caps)' failed

This patch bails out decide_allocation() if the caps aren't fixed.
