6.6-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 01aed663e6c421aeafc9c330bda630976b50a764 ]
There is no need to free the reset_data structure if the recovery is unsuccessful and the reset is synchronous. The function adf_dev_aer_schedule_reset() handles the cleanup properly. Only asynchronous resets require such structure to be freed inside the reset worker.
