Revert "sctp: fix call to SCTP_CMD_PROCESS_SACK in sctp_cmd_interpreter()"

This reverts commit de77b7955c3985ca95f64af3cb10557eb17eacee, which was
commit f6e80abeab928b7c47cc1fbf53df13b4398a2bec upstream.

This fix was only appropriate for Linux 3.7 onward, and introduced a
regression when applied to earlier versions.
