A slightly modified take on Jeff's earlier patches, tested with
both NFSv3 and NFSv4.1 via simple fault injection in
svc_rqst_replace_page().
In general I'm in favor of more rq_pages bounds checking by
replacing direct modification of the rq_respages and rq_next_page
fields with accessor functions.

SUNRPC: add bounds checking to svc_rqst_replace_page
NFSD: Watch for rq_pages bounds checking errors in nfsd_splice_actor()

nfsd: don't replace page in rq_pages if it's a continuation of last page
