drm/amdgpu: adjust the kfd reset sequence in reset sriov function

Browse source

This change revert previous commits:
9f4f2c1a35 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")
271fd38ce5 ("drm/amdgpu: move kfd post_reset out of reset_sriov function")

This change moves the amdgpu_amdkfd_pre_reset to an earlier place
in amdgpu_device_reset_sriov, presumably to address the sequence issue
that the first patch was originally meant to fix.

Some register access(GRBM_GFX_CNTL) only be allowed on full access
mode. Move kfd_pre_reset and  kfd_post_reset back inside reset_sriov
function.

Fixes: 9f4f2c1a35 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")
Fixes: 271fd38ce5 ("drm/amdgpu: move kfd post_reset out of reset_sriov function")
