virgl: fix virgl_bo_transfer_{put, get} box struct copy

Commit 3dfe61ed6ec6 ("gallium: decrease the size of pipe_box - 24 -> 16
bytes") changed the size of pipe_box, but the virgl code was relying on
pipe_box and drm_virtgpu_3d_box structs having the same size/layout doing
a struct copy. Copy the fields one by one instead.
