The added CRYPTO_ALG_KERN_DRIVER_ONLY indicates whether a cipher
is only available via a kernel driver. If the cipher implementation
might be available by using an instruction set or by porting the
kernel code, then it must not be set.

Who is going to use this? For one it's not type-safe as we try
to avoid directly using crypto_tfm in kernel code.

I needed this function in order to access the new flag without
relying on the structure format. The available crypto_tfm_alg_type() 
would apply a mask and remove it, thus I added this function.
