Su Yue f37fba66a4 btrfs: prevent NULL pointer dereference in extent_io_tree_panic
commit 29b665cc51e8b602bf2a275734349494776e3dbc 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: 05912a3c04eb ("btrfs: drop extent_io_ops::tree_fs_info callback")
