  conntrack: Fix possibly uninitialized memory.

There are a few cases where struct 'conn_key' padding may be unspecified
according to the C standard.  Practically, it seems implementations don't
have issue, but it is better to be safe. The code paths modified are not
hot ones.  Fix this by doing a memcpy in these cases in lieu of a
structure copy.

Found by inspection.
