psql: Fix tab completion for DROP INDEX CONCURRENTLY

Browse Source 
psql offered CASCADE after DROP INDEX CONCURRENTLY and an index name,
even though CASCADE is not supported with CONCURRENTLY. Offer only
RESTRICT in this case, while retaining both CASCADE and RESTRICT
for ordinary DROP INDEX.

Backpatch to all supported versions.
