btrfs-progs: check link_subvol name base
In principle, link_subvol() can be given an abitrary string as the name
of the saved subvolume. It copies it into a fixed-size stack buffer and
then uses it as dirent names without testing its length.
This limits its length to BTRFS_NAME_LEN. This was found by static
analsys.
