Anna Schumaker 39d0d3bdf7 NFS: Fix a tracepoint NULL-pointer dereference 
Running xfstest generic/013 with the tracepoint nfs:nfs4_open_file
enabled produces a NULL-pointer dereference when calculating fileid and
filehandle of the opened file.  Fix this by checking if state is NULL
before trying to use the inode pointer.
