lib/crypto: poly1305: Use memzero_explicit() in poly1305_final()
Use memzero_explicit() instead of a plain struct assignment to guarantee
zeroization of the 'struct poly1305_desc_ctx'.
Note that dead store elimination was only theoretically possible with
link-time optimization here. But it's still worth fixing.
