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.

Remove active_hw_rq and it's protecting queue_lock, they are unused.

User 32bit atomic for hw_rq_count, 64bits for counting to three is a bit
overkill.

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.
