commit f6fc6bc0b8e0bb13a210bd7386ffdcb1a5f30ef1 upstream.
These warnings were found by running 'make C=2 M=net/sctp/'.
Commit d4d6fb5787a6 ("sctp: Try not to change a_rwnd when faking a SACK from SHUTDOWN.") expected to use the peers old rwnd and add our flight size to the a_rwnd. But with the wrong Endian, it may not work as well as expected.
So fix it by converting to the right value.
