The fence in the array may be skipped if wait_all is false,
thus the related callback is not initialized with list head.
So removing this kind callback will cause NULL pointer reference.

Rename the function and update the related code with this modified function.
Add the new parameter of bool wait_all.

If wait_all is true, it will return when all fences are signaled or timeout.
If wait_all is false, it will return when any fence is signaled or timeout.

The problem now is that we don't necessarily call amdgpu_ib_get()

Better require that the memory is already zeroed.
