[ Upstream commit a1794de8b92ea6bc2037f445b296814ac826693e ]
As the annotation says in sctp_do_8_2_transport_strike():
"If the transport error count is greater than the pf_retrans threshold, and less than pathmaxrtx ..."
It should be transport->error_count checked with pathmaxrxt, instead of asoc->pf_retrans.
