[COMMITTED PATCH] Remove unnecessary mutex locks from tst-tls-atexit test case

[Siddhesh Poyarekar <siddhesh@redhat.com>]

The locks don't synchronize with anything - they were likely
introduced initially to synchronize with some main thread code, but
that is no longer evident.

Committed as obvious.
