When the "reservation_key" option is set to "file" and Register command
is run with both the current Reservation Key and a new Service Action
Reservation Key, mpathpersist will change the registration, but will not
update the prkeys file. This means that future paths that come online
will not be able to register, since multipathd is still using the old
reservation key. Fix this.
