[PATCH net-next v2] selftests: tls: fix warning of uninitialized variable

[Ankit Khushwaha]

In 'poll_partial_rec_async' a uninitialized char variable 'token' with
is used for write/read instruction to synchronize between threads
via a pipe.

tls.c:2833:26: warning: variable 'token' is uninitialized
      		   when passed as a const pointer argument

Initialize 'token' to '\0' to silence compiler warning.

Hi Ankit,

Thanks for the update. Overall this seems good to me, however,
net-next is currently closed.

## Form letter - net-next-closed

The merge window for v6.19 has begun and therefore net-next has closed
for new drivers, features, code refactoring and optimizations. We are
currently accepting bug fixes only.

Please repost when net-next reopens.

Due to a combination of the merge-window, travel commitments of the
maintainers, and the holiday season, net-next will re-open after
2nd January.

RFC patches sent for review only are welcome at any time.

See: https://www.kernel.org/doc/html/next/process/maintainer-netdev.html#development-cycle

FWIW after Simon made this comment more fixes for various ksft warnings
got posted, I think we should apply them now and to be consistent I'll
also take this one.

Understood. I'm always a little unsure where selftest changes should best land.

In any case, feel free to add my tag as this does look good to me.
