[PATCH 3/4] drm/ttm: simplify ttm_bo_move_memcpy remove useless arg

[j.glisse at gmail.com]

From: Jerome Glisse <jglisse at redhat.com>

ttm_bo_move_memcpy have no use to know if it can wait on
reserve or wait on gpu as there is no such wait in this helper.
Doesn't care either to know if it's an eviction, memcpy
is not a GPU pipelineable case.
