You can't do it. If you don't need to distinguish NA's and missing points
(that is (x,y) pairs that are completely absent from the data, as opposed to
being present with a z-value of NA), you can use panel.fill() to fill the
background with your 'NA' color. Something like
levelplot(...
panel = function(...) {
panel.fill(col = "red")
panel.levelplot(...)
})
Otherwise, change NA's to some suitable number before plotting.
