Clang-tidy correctly notices that after exiting std:call_once a couple
of globals are left pointing to local variables that go out of scope.
This isn't a problem, because the globals are only ever used by
std::call_once and it will re-init them before the next use. Zero the
variables out just for clang-tidy, to prevent the warnings.

	PR libstdc++/82481
	* include/std/mutex (call_once): Suppress clang-tidy warnings about
	dangling references.

Tested powerpc64le-linux, committed to trunk.
