dpaa_1588: fix defective processing of circular buffer
There was a defective processing after finding the desired item.
circ_buf->tail should not be pointed to idx+1, which will cause
the drop of the valid items after idx, it should be pointed to
tail+1. when buffer is full, we remove the oldest entry.
