* Check that the initial memory was actually allocated before writing to
it
* Don't pass 16 to CryptUnprotectData as the ppszDataDescr parameter
because it is not a valid LPWSTR
* Don't leak memory in the event that CryptUnprotectData by ensuring mem
and addr are always free'ed
* Combine free calls into one for speed
* Don't assume the sessions is ARCH_X64 if it is not ARCH_X86 because
that may change some day
