drm/amdgpu: Protect the amdgpu_bo_list list with a mutex v2
Protect the struct amdgpu_bo_list with a mutex. This is used during command
submission in order to avoid buffer object corruption as recorded in
the link below.
v2 (chk): Keep the mutex looked for the whole CS to avoid using the
list from multiple CS threads at the same time.
