This patch dumps general and master registers at the end of transactions when debugging is enabled. Previously, registers were only dumped before submitting new descriptors (at the beginning of transactions). This helps debugging if some registers change as result of a failed transaction (e.g. bits are set in the ERRSTS general register).
