[PATCH][next] net/handshake: remove redundant assignment to variable ret

[Colin Ian King]

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:
net/handshake/tlshd.c:216:2: warning: Value stored to 'ret' is never
read [deadcode.DeadStores]
