Revert "msm: kgsl: Enable UCHE out of bounds checking"

This reverts commit 82b160ff.
It's better to disable UCHE OOB error and get a pagefault instead
that can be analyzed by getting a snapshot. With a UCHE OOB we
cannot reliably stop the GPU on it's tracks but we can do so
with a pagefault so it's better for debugging.
