btrfs: remove unnecessary variable shadowing in btrfs_invalidatepage()

Browse Source 
In btrfs_invalidatepage() we re-declare @tree variable as
btrfs_ordered_inode_tree.

Since it's only used to do the spinlock, we can grab it from inode
directly, and remove the unnecessary declaration completely.
