crypto: remove redundant type flags from tfm allocation
Some crypto API users allocating a tfm with crypto_alloc_$FOO() are also
specifying the type flags for $FOO, e.g. crypto_alloc_shash() with
CRYPTO_ALG_TYPE_SHASH. But, that's redundant since the crypto API will
override any specified type flag/mask with the correct ones.
So, remove the unneeded flags.
This patch shouldn't change any actual behavior.
