amd/amdkfd: Use dma_fence_check_and_signal()

Browse Source 
amdkfd is one of the few users which relies on the return code of
dma_fence_signal(), which, so far, informs the caller whether the fence
had already been signaled.

As there are barely any users, dma_fence signaling functions shall get
the return value void. To do so, the few users must be ported to a
function which preserves the old behavior.

Replace the call to dma_fence_signal() with one to
dma_fence_check_and_signal().
