tcp: fix Fast Open key endianness

[ Upstream commit c860e997e9170a6d68f9d1e6e2cf61f572191aaf ]

Fast Open key could be stored in different endian based on the CPU.
Previously hosts in different endianness in a server farm using
the same key config (sysctl value) would produce different cookies.
This patch fixes it by always storing it as little endian to keep
same API for LE hosts.
