[tklock] Delay tklock removal until exit from LPM state is finished

While device is locked, removing tklock is not allowed and get substituted
with "show device unlock" request. If these get emitted while LPM display
state is active, devicelock ui can get confused.

When leaving LPM_ON state, delay tklock processing until the display
state transition is finished.
