Subject: [PATCH] build: cmake: fix -fno-sanitize-address-use-after-scope for
 CQL parser

The CMake build had -fsanitize-address-use-after-scope (enable) when
it should have been -fno-sanitize-address-use-after-scope (disable).

The comment on lines 24-25 of cql3/CMakeLists.txt explains the intent:
the use-after-scope sanitizer uses too much stack space on CqlParser
and overflows the stack. The Python-ninja path in configure.py:2801-2802
correctly had -fno-sanitize-address-use-after-scope.

Found by black-box comparison of compiler flags between the Python-ninja
and CMake build paths (ninja -nv output, debug mode, CqlParser.o):

  Python-ninja: -fno-sanitize-address-use-after-scope  (correct: disable)
  CMake:        -fsanitize-address-use-after-scope      (wrong: enable)

Closes scylladb/scylladb#29439
