SUNRPC: Fix sockaddr handling in svcsock_accept_class trace points
[ Upstream commit 16720861675393a35974532b3c837d9fd7bfe08c ]
Avoid potentially hazardous memory copying and the needless use of
"%pIS" -- in the kernel, an RPC service listener is always bound to
ANYADDR. Having the network namespace is helpful when recording
errors, though.
Fixes: a0469f46faab ("SUNRPC: Replace dprintk call sites in TCP state change callouts")
