[CI 2/5] drm/ttm: return ENOSPC from ttm_bo_mem_space

[Thomas Hellström]

From: Christian König <ckoenig.leichtzumerken at gmail.com>

Only convert it to ENOMEM in ttm_bo_validate.

This allows ttm_bo_validate to distinct between an out of memory
situation and just out of space in a placement domain.
