crypto: iaa - Fix potential use after free bug

In the Linux kernel, the following vulnerability has been resolved:

crypto: iaa - Fix potential use after free bug

The free_device_compression_mode(iaa_device, device_mode) function frees
"device_mode" but it iss passed to iaa_compression_modes[i]->free() a few
lines later resulting in a use after free.

The good news is that, so far as I can tell, nothing implements the
->free() function and the use after free happens in dead code.  But, with
this fix, when something does implement it, we'll be ready.  :)

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
