There is a socket associated with this fl_create() request, please
pass it into fl_create() from it's caller, and thus down into
datagram_send_ctl(), instead of just passing NULL.

Then, since a valid sk is always passed in, you can elide the NULL
check on 'sk' down at the bottom of these code paths.

Thanks.
