SUNRPC: Don't auto-disconnect from the local rpcbind socket
commit
00326ed6442c66021cd4b5e19e80f3e2027d5d42 upstream.
There is no need for the kernel to time out the AF_LOCAL connection to
the rpcbind socket, and doing so is problematic because when it is
time to reconnect, our process may no longer be using the same mount
namespace.
