Re: [PATCH] drm/i915/ttm: Return some errors instead of trying memcpy move

The i915_ttm_accel_move() function may return error codes that should be propagated further up the stack rather than consumed assuming that the accel move failed and could be replaced with a memcpy move.

For -EINTR, -ERESTARTSYS and -EAGAIN, just propagate those codes, rather than retrying with a memcpy move.
