[CRYPTO] api: Rename crypto_alg_get to crypto_mod_get

The functions crypto_alg_get and crypto_alg_put operates on the crypto
modules rather than the algorithms.  Therefore it makes sense to call
them crypto_mod_get and crypto_alg_put respectively.

This is needed because we need to have real algorithm reference counters
for parameterised algorithms as they can be unregistered from below by
when their parameter algorithms are themselves unregistered.
