idpf: remove duplicate defines in IDPF_CAP_RSS

Remove duplicate defines from the OR operation when defining IDPF_CAP_RSS.

Duplicate definitions were introduced when IDPF_CAP_RSS was originally
defined and were left behind and went unnoticed during a previous commit
that renamed them. Review of the original out-of-tree code confirms these
duplicates were the result of a typing error.

Remove the duplicates to clean up the code and avoid potential confusion.
Also verify no other duplicate occurrences of these defines exist
elsewhere in the codebase.
