CC Mode: Don't propertize parens in macros incorrectly

Parentheses in macros were getting incorrectly propertized with
the '(1) (punctuation) syntax-table text property.  This was
due to a typo in the patch "CC Mode: Rationalize and optimize
cache invalidation (1)" from 2024-10-06.  Correct this.

* lisp/progmodes/cc-mode.el (c-depropertize-CPP): Move the
first c-clear-syntax-table-with-value-trim-caches invocation
from inside the enclosing `when' form to after it.
