btrfs: export: handle invalid inode or root reference in btrfs_get_pa…
…rent() [ Upstream commit 26b66d1 ] The get_parent handler looks up a parent of a given dentry, this can be either a subvolume or a directory. The search is set up with offset -1 but it's never expected to find such item, as it would break allowed range of inode number or a root id. This means it's a corruption (ext4 also returns this error code).
