crypto: algif_aead - fix uninitialized ctx->init

In skcipher_accept_parent_nokey() the whole af_alg_ctx structure is
cleared by memset() after allocation, so add such memset() also to
aead_accept_parent_nokey() so that the new "init" field is also
initialized to zero. Without that the initial ctx->init checks might
randomly return true and cause errors.

While there, also remove the redundant zero assignments in both
functions.

Found via libkcapi testsuite.
