zms: unable to compile with `CONFIG_ZMS_LOOKUP_CACHE=n`

[JordanYates]

Describe the bug

The ZMS subsystem no longer compiles on Zephyr v4.2 with CONFIG_ZMS_NO_DOUBLE_WRITE=y and CONFIG_ZMS_LOOKUP_CACHE=n
The wlk_addr variable is used but not declared under that configuration.

zephyr/subsys/fs/zms/zms.c

Lines 1487 to 1495 in 663da23

	#ifdef CONFIG_ZMS_LOOKUP_CACHE
	uint64_t wlk_addr = fs->lookup_cache[zms_lookup_cache_pos(id)];
	if (wlk_addr == ZMS_LOOKUP_CACHE_NO_ADDR) {
	goto no_cached_entry;
	}
	#else
	wlk_addr = fs->ate_wra;
	#endif /* CONFIG_ZMS_LOOKUP_CACHE */

Introduced in PR #87792 (commit 42b9b5a)
