[QNX} Remove adjustBufferSize from the egl window

setGeometry will adjust the buffer for an egl window when a egl surface is created.
Adjusting the buffer somewhere else can be potentially harmful. Another reason is that
every egl window has a buffer on its own (unlike raster windows) so we do not have to
check if we have to create a buffer after reparanting.
