SCTP does not support IP_LOCAL_PORT_RANGE and we know it,
so use XFAIL instead of SKIP.

[wrt our earlier discussion off-list]

You were right, this test succeeds if I delete SKIP for SCTP.
Turns out IP_LOCAL_PORT_RANGE works for SCTP out of the box after all.

What I didn't notice earlier is that sctp_setsockopt() delegates to
ip_setsockopt() when level != SOL_SCTP.

CC'ing Marcelo & Xin, to confirm that this isn't a problem.

Yes, SCTP supports ip_local_port_range by calling
inet_sk_get_local_port_range() in sctp_get_port(), similar to TCP/UDP.

Well, that's embarassing.

I see that I've updated sctp stack to use inet_sk_get_local_port_range()
in 91d0b78c5177 ("inet: Add IP_LOCAL_PORT_RANGE socket option").

Thanks for confirming, Xin.

It's clearly an overside on my side. That SKIP in tests should have
never been there. I will send a fixup.
