concat: dot not reset pad states too early

Browse source 
Resetting the flushing state of the pads at the end of the
PAUSED_TO_READY transition will make pads handle serialized
queries again which will wait for non-active pads and might
cause deadlocks when stopping the pipeline.

Move the reset to the READY_TO_PAUSED instead.
