crypto: api - Call type show function before legacy for proc
This patch makes /proc/crypto call the type-specific show function if one is present before calling the legacy show functions for cipher/digest/compress. This allows us to reuse the type values for those legacy types. In particular, hash and digest will share one type value while shash is phased in as the default hash type.
