NLM: Set address family before calling nlm_host_rebooted()

The nlm_host_rebooted() function uses nlm_cmp_addr() to find an
nsm_handle that matches the rebooted peer. In order for this to work,
the passed-in address must have a proper address family.

This fixes a post-2.6.28 regression introduced by commit 781b61a6, which
added AF_INET6 support to nlm_cmp_addr(). Before that commit,
nlm_cmp_addr() didn't care about the address family; it compared only
the sin_addr.s_addr field for equality.

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.)
