BUILD: threads: fix pthread_mutex_unlock when !USE_THREAD

Commit 048368ef6 ("MINOR: deinit: always deinit the init_mutex on
failed initialization") added the missing unlock but forgot to
condition it on USE_THREAD, resulting in a build failure. No
backport is needed.

This addresses oss-fuzz issue 36426.
