Remove useless & unsafe unlock/lock codeaccepted/tizen/unified/x/20240226.135043accepted/tizen/unified/riscv/20240108.035927accepted/tizen/unified/20240226.134013accepted/tizen/unified/20240105.165031accepted/tizen_unified_riscv

 - there is no blocking function in tizen_window_enqueue_buffer_with_damage
 - So there is no blocking to other EGL calls
 - In additionally, it can cause some broken situation in multi-threaded egl api call,
 - because of display's Mutex protection is not working during unlocked time.
