In tcp_hc_insert() we may have the case where we have hit the global
cache size limit but this bucket row is empty.  Normally we want to
recycle the oldest entry in the bucket row.  If there isn't any the
TAILQ_REMOVE leads to a panic by trying to remove a non-existing
element.  Fix this by just returning NULL and failing the insert.
This is not a problem as the TCP hostache is only advisory.
