drm/amdgpu: no rlcg legacy read in SRIOV case
rlcg legacy read is not available in SRIOV configration.
Otherwise, gmc_v9_0_flush_gpu_tlb will always complain
timeout and finally breaks driver load.
v2: bypass read in amdgpu_virt_get_rlcg_reg_access_flag (from Victor)
Fixes: 97d1a3b967a3cb ("drm/amdgpu: switch to get_rlcg_reg_access_flag for gfx9")
