Fix Additional after homing options MarlinFirmware#26469

Fix error that if homing independent axis X or Y that the other would use the blocking move to defined position and if un-homed Axis was in a position to cause motor to slam it into frame / end stop and grind until it "thinks" its at your position.  Now if there is a home needed error it will not send said axis to position.

tested a few times with sending home to each axis independently and then disabling steppers.  Seems to catch as needed.
