Hello,

Here is quick fix for btrfs set lable ioctl(2) based on v5, it does label length check up with
strnlen() to avoid searching a zero could go beyond the page limit touching an un-mapped page
and raising an segmentation fault with strlen().


V6->v5:
- Improve the input label string validation with strnlen().
