drm/amdgpu: Correct amdgpu_amdkfd_total_mem_size calculation
amdkfd_total_mem_size is the size of total GPUs vram plus system memory
to estimate page tables memory usage and leave enough VRAM room for page
tables allocation.
Calculate amdkfd_total_mem_size in amdgpu_amdkfd_device_probe is
incorrect because adev->gmc.real_vram_size is still 0 called from
amdgpu_device_ip_early_init. Move the calculation
to amdgpu_amdkfd_device_init to get the correct VRAM size.
Do reverse calculation in amdgpu_amdkfd_device_fini_sw to support
hot-unplugging GPUs.
