Santosh Shilimkar dc205a8d34 rds: avoid version downgrade to legitimate newer peer connections 
Connections with legitimate tos values can get into usual connection
race. It can result in consumer reject. We don't want tos value or
protocol version to be demoted for such connections otherwise
piers would end up different tos values which can results in
no connection. Example a peer initiated connection with say
tos 8 while usual connection racing can get downgraded to tos 0
which is not desirable.

Patch fixes above issue introduced by commit
commit d021fabf52 ("rds: rdma: add consumer reject")
