    Save and restore AST_FLAG_BRIDGE_HANGUP_DONT on attended transfer.

    ast_bridge_call() clears AST_FLAG_BRIDGE_HANGUP_DONT. But during an attended
    transfer, ast_bridge_call() is called for a second bridge on the same channel,
    and it clears that flag, which still needs to get set for when the original
    ast_bridge_call() gets control back and checks it.
