tcp: tweak tcp_sock_write_txrx size assertion
I forgot 32bit arches might have 64bit alignment for u64
fields.
tcp_sock_write_txrx group does not contain pointers,
but two u64 fields. It is possible that on 32bit kernel,
a 32bit hole is before tp->tcp_clock_cache.
I will try to remember a group can be bigger on 32bit
kernels in the future.
With help from Vladimir Oltean.
