crypto: cryptd - use crypto_grab_shash() and simplify error paths
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.
