fix ENABLE_MAP unbound variable in reporting block

Browse Source 
set +u was added around the ENGINE_BLOCK for-loops but the reporting
lines after ok "Updated settings.yml" still ran under set -u.
bash < 4.4 throws "unbound variable" for ${#ENABLE_MAP[@]} when the
associative array is empty (no --enable-engines argument was given).

Add set +u before the Disabled/Re-enabled info lines; it already covers
the ${#DISABLE_MAP[@]} reference at the end of the script.
