drivers/crypto: do not create unique name internally

Crypto devices of the same type could be initialized
with the same name, since internally this name was suffixed
with an index.

Since commit <dda987315ca2> ("vdev: make virtual bus use its
device struct"), this is not allowed anymore.

Therefore, there is no need to create an unique name
at device initialization.
