Unbinding doesn't always lead to unconditional destruction of vma. This destruction avoidance happens if vma is part of execbuffer relocation list or if vma is being considered for eviction in i915_gem_evict_something().
For those other users, mark the vma unbound so that the correct state of this vma is preserved.
