btrfs: tree-checker: adjust error code for header level check
The whole tree checker returns EUCLEAN, except the one check in
btrfs_verify_level_key(). This was inherited from the function that was
moved from disk-io.c in 2cac5af16537 ("btrfs: move
btrfs_verify_level_key into tree-checker.c") but this should be unified
with the rest.
