Some updates to the error path for delayed dir index insertion failure,
motivated by a recent syzbot report:

Details in the changelogs.
v2: Fixed error path in patch 2 to release delayed item before unlocking
the delayed node. Added patch 3 to prevent such mistakes in the future.
Filipe Manana (3):
btrfs: improve error message after failure to add delayed dir index item
btrfs: remove BUG() after failure to insert delayed dir index item
btrfs: assert delayed node locked when removing delayed item
