Remove an extraneous call to soisconnected() in syncache_socket(), introduced with rS261242
The useful and expected soisconnected() call is done in tcp_do_segment().
Has been found as part of PR:212920 investigation.
Improve slightly (~2%) the maximum number of TCP accept per second.
As far as I can tell this is good. I have a box serving large volume of internet facing traffic with a data accept filter.
As Kevin mentioned, this looks good on prod traffic at llnw.
Thanks for your time on this review, will push this change as soon as D8211: Fix a double-free when an inp transitions to INP_TIMEWAIT state after having been dropped. is complete.
