For raw IP packets rip_input() traverses the loop of all PCBs. From
there it calls sbappendaddr() while holding the raw table mutex.
This ends in sorwakeup() where we finally grab the kernel lock while
holding a mutex. Witness detects this misuse.
Use the same solution as for PCB notify. Collect the affected PCBs
in a temporary list. The list is protected by exclusive net lock.
