[PATCH] drm/xe/vm: Do not dma_fence_put zero fences in err_out path

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

It is not necessary to iterate over and dma_fence_put current_fence
fences in the err_out path of ops_execute because current_fences cannot
be non-zero when jumping to that section of code.

Caught by static analysis.
