Touchscreen spurious event fix

[JamesH65]

Touchscreen driver was not checking event type,
which meant bad coords that arrived with the
finger up event were being used, causing this
spurious coordinate event.

Fix is to ignore all finger up events.

I'd forgotten to PR this, and we have customers for whom this is an important fix.

Didn't we already merge #2207?

I couldn't find it in the kernel tree so I presumed I hadn't PR'd it. However, it is quite possible it is already there, I seem to remember it going in. If already there, please ignore me!
