[PATCH v5.10-v6.6] btrfs: don't BUG_ON on ENOMEM from btrfs_lookuip_extent_info() in walk_down_proc()

[Keerthana K <keerthana.kalyanasundaram@xxxxxxxxxxxx>]

From: Josef Bacik <josef@xxxxxxxxxxxxxx>

[ Upstream commit a580fb2c3479d993556e1c31b237c9e5be4944a3 ]

We handle errors here properly, ENOMEM isn't fatal, return the error.
