Steven Rostedt (VMware) 4397f04575 tracing: Fix possible double free on failure of allocating trace buffer ... Jing Xia and Chunyan Zhang reported that on failing to allocate part of the tracing buffer, memory is freed, but the pointers that point to them are not initialized back to NULL, and later paths may try to free the freed memory again. Jing and Chunyan fixed one of the locations that does this, but missed a spot.
