[ Upstream commit bf75ad096820fee5da40e671ebb32de725a1c417 ]
When client initialization goes through server trunking discovery, it schedules the state manager and then sleeps waiting for nfs_client initialization completion.
The state manager can fail during state recovery, and specifically in lease establishment as nfs41_init_clientid() will bail out in case of errors returned from nfs4_proc_create_session(), without ever marking the client ready. The session creation can fail for a variety of reasons e.g. during backchannel parameter negotiation, with status -EINVAL.
The error status will propagate all the way to the nfs4_state_manager but the client status will not be marked, and thus the mount process will remain blocked waiting.
Fix it by adding -EINVAL error handling to nfs4_state_manager().
