Since r353292 on input path we are always in network epoch, when
we lookup PCBs.  Thus, do not enter epoch recursively in
in_pcblookup_hash() and in6_pcblookup_hash().  Same applies to
tcp_ctlinput() and tcp6_ctlinput().

This leaves several sysctl(9) handlers that return PCB credentials
unprotected.  Add epoch enter/exit to all of them.
