[ Upstream commit 6fcd4267a840d0536b8e5334ad5f31e4105fce85 ]
Building kcsan_test with structleak plugin enabled makes the stack frame size to grow.
kernel/kcsan/kcsan_test.c:704:1: error: the frame size of 3296 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
Turn off the structleak plugin checks for kcsan_test.
