Chengguang Xu 7e35eab958 btrfs: replace empty string with NULL when getting attribute length in btrfs_get_acl ...

In btrfs_get_acl() the first call of btr_getxattr() is for getting the
length of attribute, the value buffer is never used in this case. So
it's better to replace empty string with NULL.
