Revert "pad: don't check twice for changed caps per push"

We need to check the pad caps on the srcpad as well as on the sinkpad. Revert
this commit as it removes the check on the srcpad and can leave the srcpad
unnegotiated (or negotiated with wrong caps)

This reverts commit 07dc1e5b49580a89bfef27ff27476d51fb3ce2c2.
