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.
