net: fix nla_strcmp to handle more then one trailing null character
[ Upstream commit 2c16db6c92b0ee4aa61e88366df82169e83c3f7e ]
Android userspace has been using TCA_KIND with a char[IFNAMESIZ]
many-null-terminated buffer containing the string 'bpf'.
This works on 4.19 and ceases to work on 5.10.
I'm not entirely sure what fixes tag to use, but I think the issue
was likely introduced in the below mentioned 5.4 commit.
