The variable is being assigned an value and then is being re-assigned
a new value in the next statement. The assignment is redundant and can
be removed.
Cleans up clang scan build warning:

key_serial_t fields are signed integers. Use nla_get/put_s32 for
those to avoid implicit signed conversion in the netlink protocol.

Enable the upper layer protocol to specify the SNI peername. This
avoids the need for tlshd to use a DNS lookup, which can return a
hostname that doesn't match the incoming certificate's SubjectName.

These verify the API contracts and help exercise lifetime rules for
consumer sockets and handshake_req structures.
One way to run these tests:
./tools/testing/kunit/kunit.py run --kunitconfig ./net/handshake/.kunitconfig

To enable kernel consumers of TLS to request a TLS handshake, add
support to net/handshake/ to request a handshake upcall.
This patch also acts as a template for adding handshake upcall
support for other kernel transport layer security providers.
