NFSv4.1: fix mount hang after CREATE_SESSION failure

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().
