video: tegra: host: Skip expired pre-fences
Currently, nvhost pushes pre-fence waits always to the channel -
even if the fence would already be passed. In rare cases this causes
a wrapping issue when the hardware does not recognise that the
syncpoint threshold has already passed.
This patch modifies the code so that we check the fence value before
pushing the wait to the push buffer.
