drm/prime: fix up handle_to_fd ioctl return value

drm/prime: add return check for dma_buf_fd
the failure case handling was fixed up. But in the case when we
already had the buffer exported it changed the return value:
Previously we've return 0 on success, now we return the fd.
This ABI change has been caught by i-g-t/prime_self_import/with_one_bo.
