[ Upstream commit 304791255a2dc1c9be7e7c8a6cbdb31b6847b0e5 ]
If the initial attempt at trunking detection using the krb5i auth flavor fails with -EACCES, -NFS4ERR_CLID_INUSE, or -NFS4ERR_WRONGSEC, then the NFS client tries again using auth_sys, cloning the rpc_clnt in the process. If this second attempt at trunking detection succeeds, then the resulting nfs_client->cl_rpcclient winds up having cl_max_connect=0 and subsequent attempts to add additional transport connections to the rpc_clnt will fail with a message similar to the following being logged:
[502044.312640] SUNRPC: reached max allowed number (0) did not add transport to server: 192.168.122.3
