Use NFSD_SLOT_CACHE_SIZE size buffers for sessions DRC instead of holding nfsd pages in cache. Connectathon testing has shown that 1024 bytes for encoded compound operation responses past the sequence operation is sufficient, 512 bytes is a little too small. Set NFSD_SLOT_CACHE_SIZE to 1024. Allocate memory for the session DRC in the CREATE_SESSION operation to guarantee that the memory resource is available for caching responses. Allocate each slot individually in preparation for slot table size negotiation. Remove struct nfsd4_cache_entry and helper functions for the old page-based DRC. The iov_len calculation in nfs4svc_encode_compoundres is now always correct. Replay is now done in nfsd4_sequence under the state lock, so the session ref count is only bumped on non-replay. Clean up the nfs4svc_encode_compoundres session logic. The nfsd4_compound_state statp pointer is also not used. Remove nfsd4_set_statp(). Move useful nfsd4_cache_entry fields into nfsd4_slot.
