Hi,

the first commit removes obviously unused code (at least I don't know about any arch where size_t would be signed type)

The second patch is in reaction to resource leaks warning issued by coverity scan. I'm not familiar with pam modules, but at least what I got from documentation, until pam_set_data function returns success (and register cleanup_snapshot_num() routine), memory referenced by snapshot_num_out pointer should by freed by worker code, I think.

Hope it helps.
