f67eb9ce07 Revert "radv/amdgpu: workaround a kernel bug when replacing sparse mappings"
This workaround was added temporarily but it can actually cause
stuttering in some games like Forza Horizon 5.

The kernel fix
(https://lists.freedesktop.org/archives/amd-gfx/2023-June/094648.html)
landed in some stable kernels (5.15.121+, 6.1.40+ and 6.4.5+). Sadly,
older stable kernels don't have it, so you might experiment random GPU
hangs in games that use sparse mapping. Please ensure your kernel is
up-to-date for the best experience.

This reverts commit 9b00867327.
