nfsd: fix failure to set eof in readdir in some situations
Before 14f7dd632011bb89c035722edd6ea0d90ca6b078 "[PATCH] Copy XFS readdir hack into nfsd code", readdir_cd->err was reset to eof before each call to vfs_readdir; afterwards, it is set only once. Similarly, c002a6c7977320f95b5edede5ce4e0eeecf291ff "[PATCH] Optimise NFS readdir hack slightly", can cause us to exit without nfserr_eof set. Fix this. This ensures the "eof" bit is set when needed in readdir replies. (The particular case I saw was an nfsv4 readdir of an empty directory, which returned with no entries (the protocol requires "." and ".." to be filtered out), but with eof unset.)
