drm/amdgpu: Skip emit de meta data on gfx11 with rs64 enabled

Browse Source 
commit 80d8a9ad15 upstream.

[Why]
Accoreding to CP updated to RS64 on gfx11,
WRITE_DATA with PREEMPTION_META_MEMORY(dst_sel=8) is illegal for CP FW.
That packet is used for MCBP on F32 based system.
So it would lead to incorrect GRBM write and FW is not handling that
extra case correctly.

[How]
With gfx11 rs64 enabled, skip emit de meta data.
