Make the cryptd template (in the hash case) use the new function crypto_grab_shash() to initialize its shash spawn. This is needed to make all spawns be initialized in a consistent way. This required making cryptd_create_hash() allocate the instance directly rather than use cryptd_alloc_instance(). Also simplify the error handling by taking advantage of crypto_drop_*() now accepting (as a no-op) spawns that haven't been initialized yet, and by taking advantage of crypto_grab_*() now handling ERR_PTR() names.
