[Gstreamer-openmax] [PATCH 5/5] basesink: initalize omx when changing to READY

[Felipe Contreras]

Sometimes pad_link is called after switching the state; we need to have omx
initialized always.

Based on the tunneling patch series by Frederik Vermelen (NXP), whom
also gave feedback to this patch.
