UPSTREAM: dma-buf: revert "return only unsignaled fences in dma_fence_unwrap_for_each v3"

This reverts commit 8f619737.

It turned out that this is not correct. Especially the sync_file info
IOCTL needs to see even signaled fences to correctly report back their
status to userspace.

Instead add the filter in the merge function again where it makes sense.
