Update esp3d_commands.cpp

Override new behavior in Marlin that prevent error to update screen e.g: No SD Card -> IP is not displayed because M117 is locked, so always unlock M117 output
Do not affect M111 because it is user key, so he can type M117 first to unlock if necessary, the fix only apply to auto M117 output
