ANDROID: fix up CRC issue with struct tcp_sock 



Commit 3625b684 ("tcp: fix tcp_cwnd_validate() to not forget
is_cwnd_limited") renames a field in struct tcp_sock from
max_packets_seq to cwnd_usage_seq.  This is not a real abi break as it
is not visible to external modules, but the CRC of the function
tcp_sock() is changed.  Fix this up with the __GENKSYMS__ hack to
preserve the CRC.
