drm/ttm/pool: Fix ttm_pool_alloc error path
When hitting an error, the error path forgot to unmap dma mappings and
could call set_pages_wb() on already uncached pages.
Fix this by introducing a common ttm_pool_free_range() function that
does the right thing.
v2:
- Simplify that common function (Christian König)
v3:
- Rename that common function to ttm_pool_free_range() (Christian König)
