[PATCH net 1/3] wireguard: noise: remove unused variable

["Jason A. Donenfeld" <Jason@zx2c4.com>]

This is a harmless artifact from early pre-release wireguard
development. These days, static_private is read from a shared
data structure under a read lock directly, and it doesn't need to be
copied to the stack. So remove the unused variable.
