Pull misc AFS fixes from David Howells:
 "Three miscellaneous fixes to the afs filesystem:

   - Remove some struct members that aren't used, aren't set or aren't
     read, plus a wake up that nothing ever waits for.

   - Actually set the AFS_SERVER_FL_HAVE_EPOCH flag so that the code
     that depends on it can work.

   - Make a couple of waits uninterruptible if they're done for an
     operation that isn't supposed to be interruptible"
