nfsd: Decode and send 64bit time values

commit bf8d909705e9d9bac31d9b8eac6734d2b51332a7 upstream.

The seconds field of an nfstime4 structure is 64bit, but we are assuming
that the first 32bits are zero-filled.  So if the client tries to set
atime to a value before the epoch (touch -t 196001010101), then the
server will save the wrong value on disk.
