hwc/overlay: Force pipe config if list geometry changes
Force pipes of a display, whose geometry has changed, to pass
configuration arguments using MSMFB_SET_IOCTL. This helps the driver
make additive bandwidth calculations and reject the frame if the
requirements go beyond what the hardware can support.
This change still preserves the optmization to avoid ioctl calls, in
cases where pipe params are the same but makes an exception when
list geometry changes.
