Remove redundant for-loop

Now that lcd_status_message is now initialised correctly at boot-up,
this for-loop is no longer required. Now lcd_status_message is
only set in lcd_updatestatus() which always calls lcd_finishstatus()

lcd_finishstatus() makes sure the message does not exceed 20 characters
