tcp_vu: Remove unnecessary tcp_vu_update_check() function

Because the vhost-user <-> virtio-net path ignores checksums, we usually
don't calculate them when sending packets to the guest.  So, we always
pass no_tcp_csum=true to tcp_fill_headers().  We do want accurate
checksums when capturing packets though, so the captures don't show bogus
values.

Currently we handle this by updating the checksum field immediately before
writing the packet to the capture file, using tcp_vu_update_check().  This
is unnecessary, though: in each case tcp_fill_headers() is called not very
long before, so we can alter its no_tcp_csum parameter pased on whether
we're generating captures or not.
