btrfs: zoned: fix missing RCU locking in error message when loading zone info
At btrfs_load_zone_info() we have an error path that is dereferencing
the name of a device which is a RCU string but we are not holding a RCU
read lock, which is incorrect.
Fix this by using btrfs_err_in_rcu() instead of btrfs_err().
The problem is there since commit 08e11a3db098 ("btrfs: zoned: load zone's
allocation offset"), back then at btrfs_load_block_group_zone_info() but
then later on that code was factored out into the helper
btrfs_load_zone_info() by commit 09a46725cc84 ("btrfs: zoned: factor out
per-zone logic from btrfs_load_block_group_zone_info").
Fixes: 08e11a3db098 ("btrfs: zoned: load zone's allocation offset")
