[PATCH libnetfilter_conntrack 2/2] conntrack: simplify calculation of `struct sock_fprog` length

[Jeremy Sowden <jeremy@azazel.net>]

When assigning the length to the `struct sock_fprog` object, we
calculate it by multiplying the number of `struct sock_filter` objects,
`j`, by `sizeof(struct sock_filter)` and then dividing by
`sizeof(bsf[0])`, which, since `bsf[0]` is a `struct sock_filter`, is
equal to `sizeof(struct sock_filter)`.

Remove the `sizeof` expressions and just assign `j`.
