crypto: include crypto- module prefix in template

This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause <[email protected]> Signed-off-by: Kees Cook <[email protected]> Acked-by: Mathias Krause <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
