btrfs: tree-checker: add inode extref checks

Browse source

[ Upstream commit aab9458b9f ]

Like inode refs, inode extrefs have a variable length name, which means
we have to do a proper check to make sure no header nor name can exceed
the item limits.

The check itself is very similar to check_inode_ref(), just a different
structure (btrfs_inode_extref vs btrfs_inode_ref).
