patch 9.1.0022: Coverity complains about improper use of negative value

patch 9.1.0022: Coverity complains about improper use of negative value

Problem: Coverity complains about improper use of negative value
Solution: Add a condition to validate that keytyped is larger or equal
to 0

Apparently patch 9.1.0006 made it more explicit for Coverity, that the
TOLOWER_LOC() macros do not handle negative values properly. However,
that condition has always been there even before that, so add a
condition to verify that keytyped is indeed at least 0

closes: #13824
