p11-kit commands expecting a single token/object prints confusing error upon no match

[ueno]

If there are no matching objects, the p11-kit delete-object command shows the following error:

p11-kit delete-object "pkcs11:token=nonexistent"
p11-kit: failed to find the object: The operation was cancelled

This is confusing, because there is no user interaction involved, but CKR_CANCEL is only used as a convention to tell that there is no match:
