net-2.6 [Bug-Fix][dccp]: fix oops caused after failed initialisation
dccp: fix panic caused by failed initialisation
This fixes a kernel panic reported thanks to Andre Noll:
if DCCP is compiled into the kernel and any out of the initialisation
steps in net/dccp/proto.c:dccp_init() fail, a subsequent attempt to create
a SOCK_DCCP socket will panic, since inet{,6}_create() are not prevented
from creating DCCP sockets.
This patch fixes the problem by propagating a failure in dccp_init() to
dccp_v{4,6}_init_net(), and from there to dccp_v{4,6}_init(), so that the
DCCP protocol is not made available if its initialisation fails.
