[ Upstream commit 72641d8d60401a5f1e1a0431ceaf928680d34418 ]

This workarounds are causing hangs, because I missed the fact that it
needs to be enabled for all cases and disabled when doing a resolve
pass.

So KMD only needs to whitelist it and UMD will be the one setting it
on per case.

This reverts commit 28ec02c9cbebf3feeaf21a59df9dfbc02bda3362.
