Mark Johnston 8bde6d15d1 nfsclient: Copy only initialized fields in nfs_getattr() 
When loading attributes from the cache, the NFS client is careful to
copy only the fields that it initialized.  After fetching attributes
from the server, however, it would copy the entire vattr structure
initialized from the RPC response, so uninitialized stack bytes would
end up being copied to userspace.  In particular, va_birthtime (v2 and
v3) and va_gen (v3) had this problem.

Use a common subroutine to copy fields provided by the NFS client, and
ensure that we provide a dummy va_gen for the v3 case.
