nfsd: restrict rd_maxcount to svc_max_payload in nfsd_encode_readdir
commit 9c2ece6ef67e9d376f32823086169b489c422ed0 upstream.
nfsd4_readdir_rsize restricts rd_maxcount to svc_max_payload when
estimating the size of the readdir reply, but nfsd_encode_readdir
restricts it to INT_MAX when encoding the reply. This can result in log
messages like "kernel: RPC request reserved 32896 but used 1049444".
Restrict rd_dircount similarly (no reason it should be larger than
svc_max_payload).
