This reverts commit 43fa41c1af.
The above commit disabled absolute extrude moves because it was
unclear if the code would work properly when an M221 extrude factor or
G92 offset was in use. However, since the calculation is done
relative to the raw E position and is sent as a raw E position to
gcode.cmd_G1() these modes should not matter.

Commit 402110f6 didn't actually fix absolute extrude mode. For now,
report an error if an extrude move is requested in absolute extrude
mode.
