child-create: Fix crash when retrying CHILD_SA rekeying due to a DH group mismatch 

If the responder declines our KE payload during a CHILD_SA rekeying migrate()
is called to reuse the child-create task.  But the child-rekey task then
calls the same method again.

Fixes: 32df0d81fb ("child-create: Destroy nonceg in migrate()")
