Phil Hord f0fa5f9f3e dda_lookahead.c: reduce size of ATOMIC section. 
We calculate a safe join speed in dda_join_moves using data from
two source DDA movements. We ensure the DDA values we use are sane
by atomically copying them to local variables before beginning our
calculation. But later we discard all our results if the DDA went
live in the meantime, as evidenced by changes in `DDA->live` or
`DDA->id`.

Since we will not use the results of our calculations if either of
these change, we can safely reference all the other DDA values
non-atomically. Change the ATOMIC section to protect only the
`DDA->id` values at the start.

Added by Traumflug: this costs a negligible 4 bytes binary size:

  ATmega sizes               '168   '328(P)   '644(P)     '1280
  Program:  18082 bytes      127%       59%       29%       15%
     Data:   2176 bytes      213%      107%       54%       27%
   EEPROM:     32 bytes        4%        2%        2%        1%
