drm/amdgpu: Fix VRAM BO swap issue
DRM buddy manager allocates the contiguous memory requests in
a single block or multiple blocks. So for the ttm move operation
(incase of low vram memory) we should consider all the blocks to
compute the total memory size which compared with the struct
ttm_resource num_pages in order to verify that the blocks are
contiguous for the eviction process.
v2: Added a Fixes tag
v3: Rewrite the code to save a bit of calculations and
variables (Christian)
Fixes: c9cad937c0c5 ("drm/amdgpu: add drm buddy support to amdgpu")
