Subject: [PATCH] lib: dynamic_queue_limits: Fix when built in ARCH nds32

In arch nds32, build fail with following errors:
lib/dynamic_queue_limits.c: In function 'dql_reset':
lib/dynamic_queue_limits.c:119:2: error: implicit declaration of
       function 'memset' [-Werror=implicit-function-declaration]
memset(dql, 0, offsetof(struct dql, lowest_slack));

Add <linux/string.h> fixes that.

Fixes: 36ef65b21930 ("lib: dynamic_queue_limits: use memset and offsetof ")
