Casey Bodley 827a1b7368 volume: cache volume attr results with vnetroot 
moved the FileSystemName definition back down to the kernel, so the daemon is no longer responsible for setting it.  the driver uses the string length to calculate the buffer size needed for NFS41_V_NET_ROOT_EXTENSION.FsAttrs, and copies in the FileSystemName after the first successful volume attributes upcall
