btrfs-progs: change filename limit to 255 when creating subvolume
Modify the file name length limit to meet the Linux naming convention. In addition, the file name length is always bigger than 0, no need to compare with 0 again. Issue: #145 Signed-off-by: Su Yanjun <suyj.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>
