nfsd41: Add a create session replay cache
Replace the nfs4_client cl_seqid field with a single struct nfs41_slot used
for the create session replay cache.
The CREATE_SESSION slot sets the sl_session pointer to NULL. Otherwise, the
slot and it's replay cache are used just like the session slots.
Fix unconfirmed create_session replay response by initializing the
create_session slot sequence id to 0.
A future patch will set the CREATE_SESSION cache when a SEQUENCE operation
preceeds the CREATE_SESSION operation. This compound is currently only cached
in the session slot table.
