Remove unused local

[seonyounggg]

This fixes a part of #30457
remove unused local variable tempHandle at line 62
Please check it

It should be the local to be unused, not the function call. The valid change should be changing the local to discard(_).

Given that the repo hasn't opt-in discard fully in old code, I don't suggest you to do such changes.

@huoyaoyuan You mean that Interop.VirtualAlloc(...) should be remained?

[huoyaoyuan]

@seonyounggg It must be remained because it has side effect out of the runtime.
In my opinion, changing IntPtr tmpHandle to _ is too minor and doesn't worth a PR.

Okay then I'll close this. Thanks for replying.
