nvhost: Do not crash if wait syncpt > max
If user space is waiting for a syncpt value higher than max,
nvhost_wait_timeout() panics the kernel. This panic is based on the
assumption that nobody should wait for sync points higher than indicated
by a submit from user space.
As the API has nothing to disallow waiting for future sync points not
indicated by any submit, this patch removes the panic and treats this as
a normal case.
