crypto: drbg - fix freeing of resources
commitsteinar/wifi_calib_4_9_kernelbd6227a150
upstream. During the change to use aligned buffers, the deallocation code path was not updated correctly. The current code tries to free the aligned buffer pointer and not the original buffer pointer as it is supposed to. Thus, the code is updated to free the original buffer pointer and set the aligned buffer pointer that is used throughout the code to NULL. Fixes:3cfc3b9721
