Juergen Gross 7985e875b9 tools/xenstored: make conn_delete_all_transactions() idempotent ...

conn_delete_all_transactions() should be callable in any context,
resetting ALL transaction related data.

This includes number of active transactions and the transaction
pointer in struct connection.

So reset conn->trans to NULL in conn_delete_all_transactions() and
do the cleanup for each transaction in destroy_transaction().

This avoids triggering the assert() in conn_delete_all_transactions()
in case e.g. ignore_connection() was called while an operation inside
a transaction was performed, or XS_RESET_WATCHES was called in a
transaction.

This is XSA-484 / CVE-2026-23557.
