Sync before/after setting mesh_bed_leveling_flag/homing_flag

Browse Source 
mesh_bed_leveling_flag and homing_flag should be set only when the
planner is empty as a consequence of #3100, since any operation executed
*while* the mbl/homing flag is set is considered part of the compound
instruction that generated it (G80, G28, G30, G76).

Failure in doing so can result in instructions just prior being lost,
since they're incorrectly discarded (assumed to be redone).

G1  ; lost ..
G80 ; .. if PP happens here
