virt-aa-helper: Ignore open errors again
virt-aa-helper: Ignore open errors again

virt-aa-helper used to ignore errors when opening files.
Commit a8853344994a7c6aaca882a5e949ab5536821ab5 refactored
the related code and changed this behavior. virt-aa-helper
didn't ignore open errors anymore and virt-aa-helper-test
fails.

Make sure that virt-aa-helper ignores open errors again.
