The mode of operation of the TMC tracked in drvdata->mode is defined as a local_t type. This is always checked and modified under the drvdata->spinlock and hence we don't need local_t for it and the unnecessary synchronisation instructions that comes with it. This change makes the code a bit more cleaner. Also fixes the order in which we update the drvdata->mode to CS_MODE_DISABLED. i.e, in tmc_disable_etX_sink we change the mode to CS_MODE_DISABLED before invoking tmc_disable_etX_hw() which in turn depends on the mode to decide whether to dump the trace to a buffer.
