lib: remove redundant destroyHook checks

[gurgunday]

// Fewer checks may be possible, but these cover everything.

emitDestroy already checks these now:

node/lib/internal/async_hooks.js

Lines 533 to 538 in 6f941fc

	function emitDestroyScript(asyncId) {
	// Return early if there are no destroy callbacks, or invalid asyncId.
	if (!hasHooks(kDestroy) || asyncId <= 0)
	return;
	async_wrap.queueDestroyAsyncId(asyncId);
	}

We are essentially checking the same condition twice

Also the invalid id check didn't cover undefined. I don't know if it was intentional, but in any case, since #56966, which removed enroll, I'm not sure if we can have an undefined asyncId anyway
