net/dump: Rework net-dump init functions

Browse Source 
Move the creation of the dump client from net_dump_init() into
net_init_dump(), so we can later use the former function for
dump via netfilter, too. Also rename net_dump_init() to
net_dump_state_init() to make it easier distinguishable from
net_init_dump().
