sctp: fix a type cast warnings that causes a_rwnd gets the wrong value
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. Fixes: d4d6fb5787a6 ("sctp: Try not to change a_rwnd when faking a SACK from SHUTDOWN.")
