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.
