Fix moves for DELTA for MANUAL_BED_LEVELING

- Use `line_to_current` in place of `plan_buffer_line`

Marlin/Marlin_main.cpp

     // use that as a starting point for each probe.
     //
     if (verbose_level > 2)
-      SERIAL_PROTOCOL("Positioning the probe...\n");
+      SERIAL_PROTOCOLPGM("Positioning the probe...\n");
 
     plan_buffer_line( X_probe_location, Y_probe_location, Z_start_location,
         ext_position,
