regex: pacify Coverity clean_state_log_if_needed
Problem reported by Robbie Harwood in:
https://lists.gnu.org/r/bug-gnulib/2021-12/msg00005.html
* lib/regexec.c (clean_state_log_if_needed):
Add a DEBUG_ASSERT; this both pacifies Coverity and
will help to debug in case some other change mistakenly
causes the assertion to become false.
