[PATCH 14/20] cpukit/posix/src/timertsr.c: Add _Assert()

[Joel Sherrill]

From: Josh Oguin <josh.oguin at oarcorp.com>

CodeSonar flagged this as an empty if body. Upon analysis, it turned
out to be an error that we think should never occur but if it did,
there is nothing we could do about it. It would likely just indicate
the thread was deleted before we got here. Adding the _Assert() at least
will flag this if it ever occurs during a debug build and we can discuss
what happened.
