motion: fix task to guarantee task never exits

Browse Source 
Fix motion_sense task to make sure the task never exits. Note,
before this change a task_wake(TASK_ID_MOTIONSENSE) would end
the task because task_wait_event() would return 0.

BUG=none
BRANCH=smaug
TEST=with following CL, run motion_lid test and make sure it
passes
