sctp: Prepare sctp_v4_get_dst() to dscp_t conversion.

Define inet_sk_dscp() to get a dscp_t value from struct inet_sock, so
that sctp_v4_get_dst() can easily set ->flowi4_tos from a dscp_t
variable. For the SCTP_DSCP_SET_MASK case, we can just use
inet_dsfield_to_dscp() to get a dscp_t value.

Then, when converting ->flowi4_tos from __u8 to dscp_t, we'll just have
to drop the inet_dscp_to_dsfield() conversion function.
