selftests: tls: fix warning of uninitialized variable

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.
