Move the code to reset a session from the session_reclaimer to the
nfs4_state_manager. Destroy the session, and create a new one. Treat
NFS4ERR_BADSESSION and NFS4ERR_DEADSESSION as a successful
nfs4_proc_destroy_session. Signal nfs4_proc_create_session that this is a
session reset so that the session slot table is re-used.
If the clientid is stale, set both NFS4CLNT_LEASE_EXPIRED and
NFS4CLNT_SESSION_SETUP bits and retry.
Use a switch statement in nfs4_session_recovery_handle_error for future
patche which will add handling for other errors.

[nfs41: reset session on nfs4_do_reclaim session reset error]
If nfs4_do_reclaim gets a session reset error, nfs4_recovery_handle_error
will set the NFS4CLNT_SESSION_SETUP bit, and the state manager should
continue processing to reset the session.
