AFS: Fix compilation warning

Fix the following warning:

  fs/afs/dir.c: In function 'afs_d_revalidate':
  fs/afs/dir.c:567: warning: 'fid.vnode' may be used uninitialized in this function
  fs/afs/dir.c:567: warning: 'fid.unique' may be used uninitialized in this function

by marking the 'fid' variable as an uninitialized_var.  The problem is
that gcc doesn't always manage to work out that fid is always set on the
path through the function that uses it.
