i965/skl: Don't use the PMA depth stall workaround
the system freezes soon after, causing loss of data.
[Test Case]
* installl chromium version 41.x (webgl disabled on later versions)
* open https://jbouny.github.io/fft-ocean/
* grab the ship, rotate quickly
* should freeze in a few seconds
[Regression Potential]
* none, it's a gen9 specific workaround
