bugzilla: 47457

--------------------------------

commit 29b665cc upstream.

Some extent io trees are initialized with NULL private member (e.g.
btrfs_device::alloc_state and btrfs_fs_info::excluded_extents).
Dereference of a NULL tree->private as inode pointer will cause panic.

Pass tree->fs_info as it's known to be valid in all cases.

Fixes: 05912a3c ("btrfs: drop extent_io_ops::tree_fs_info callback")
