NeilBrown 52d304eb4e locks: fix NULL-deref in generic_delete_lease 
commit 0efaa7e82f02fe69c05ad28e905f31fc86e6f08e
  locks: generic_delete_lease doesn't need a file_lock at all

moves the call to fl->fl_lmops->lm_change() to a place in the
code where fl might be a non-lease lock.
When that happens, fl_lmops is NULL and an Oops ensures.

So add an extra test to restore correct functioning.
