Btrfs: don't return ino to ino cache if inode item removal fails
commit c08db7d8d295a4f3a10faaca376de011afff7950 upstream.
In btrfs_evict_inode(), if btrfs_truncate_inode_items() fails, the inode
item will still be in the tree but we still return the ino to the ino
cache. That will blow up later when someone tries to allocate that ino,
so don't return it to the cache.
Fixes: 581bb050941b ("Btrfs: Cache free inode numbers in memory")

[bwh: Backported to 3.16:
- Pass inode, not btrfs_inode, to btrfs_orphan_del()
- Pass btrfs_root, not btrfs_fs_info, to btrfs_free_block_rsv()
- Adjust context]
