lavapipe: allow timeline progress in GetSemaphoreCounterValue 

the vulkan spec doesn't explicitly state whether this function progresses
a given semaphore's timeline, and apparently there are some cases where
it's assumed that progress occurs if this function is called in a loop
instead of WaitSemaphores, so check the current fence for completion
