Spindle activated during g0 jin M3 laser mode

[m-g-m]

During a g0 seek in M3 laser mode, the spindle (laser) can be turned on if subsequent g1 commands are fed to the planner.
This seems to be a consequence of line 195 in motion_control.c.
At this point in the code, the spindle state of future "planned" moves are immediately synchronized to the machine.
Not sure why this would be there, but it doesn't seem correct (and causes unintended laser cuts to be made across the workpiece) !

This has to be like this or cutting will not be possible when M3 is used to turn on the laser. It is a bug if it is not turned on for G0 motions as well? I'll have to check that.
