tipc: set sysctl_tipc_rmem and named_timeout right range
[ Upstream commit 4bcd4ec1017205644a2697bccbc3b5143f522f5f ]
We find that sysctl_tipc_rmem and named_timeout do not have the right minimum
setting. sysctl_tipc_rmem should be larger than zero, like sysctl_tcp_rmem.
And named_timeout as a timeout setting should be not less than zero.
Fixes: cc79dd1ba9c10 ("tipc: change socket buffer overflow control to respect sk_rcvbuf")
Fixes: a5325ae5b8bff ("tipc: add name distributor resiliency queue")
