drm/amdkfd: Fix user queue validation on Gfx7/8
commit 542c3bb836733a1325874310d54d25b4907ed10e upstream.
To workaround queue full h/w issue on Gfx7/8, when application create
AQL queue, the ring buffer bo allocate size is queue_size/2 and
map queue_size ring buffer to GPU in 2 pieces using 2 attachments, each
attachment map size is queue_size/2, with same ring_bo backing memory.
For Gfx7/8, user queue buffer validation should use queue_size/2 to
verify ring_bo allocation and mapping size.
