Don't try to fix eliminated nbtree array scan keys. Preprocessing for nbtree index scans allowed array "input" scan keys already marked eliminated during array-specific preprocessing to be "fixed up" during preprocessing proper. This allowed eliminated scan keys on DESC index columns to spurious have their strategy commuted, causing assertion failures.
To fix, teach _bt_fix_scankey_strategy to ignore these scan keys. This brings it in line with its only caller, _bt_preprocess_keys. Oversight in commit 5bf748b8, which enhanced nbtree ScalarArrayOp execution.
