dde_linux: backport fix for use-after-free reported by GCC 12 On my system, compiling dde_linux fails with `-Werror=use-after-free`. Backport the fix from mainline to get rid of the issue. Fixes #4740

linux: allow more workers when scheduling works Workers are only summoned by the manager or when there are no workers on a work queue. In case a work in front of a work queue depends on a work behind it, a deadlock may occur. To solve this Linux spawns a rescue worker using timers. Timing of Linux based drivers is currently reworked and not reliable. Therefore, we increase the number of workers that are spawned from 1 to 3 per work queue in order to resolve possible deadlocks. Fixes #4762
