crypto: skcipher - use crypto_grab_cipher() and simplify error paths
Make skcipher_alloc_instance_simple() use the new function
crypto_grab_cipher() to initialize its cipher spawn.
This is needed to make all spawns be initialized in a consistent way.
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.
