Arjun Roy 71e38a0c7c tcp: correctly handle increased zerocopy args struct size ...

[ Upstream commit e0fecb289ad3fd2245cdc50bf450b97fcca39884 ]

A prior patch increased the size of struct tcp_zerocopy_receive
but did not update do_tcp_getsockopt() handling to properly account
for this.

This patch simply reintroduces content erroneously cut from the
referenced prior patch that handles the new struct size.

Fixes: 18fb76ed5386 ("net-zerocopy: Copy straggler unaligned data for TCP Rx. zerocopy.")
