Btrfs: fix btrfs_evict_inode to handle abnormal inodes correctly
commit e8f1bc1493855e32b7a2a019decc3c353d94daf6 upstream.
This regression is introduced in
commit 3d48d9810de4 ("btrfs: Handle uninitialised inode eviction").
There are two problems,
a) it is ->destroy_inode() that does the final free on inode, not
->evict_inode(),
b) clear_inode() must be called before ->evict_inode() returns.
This could end up hitting BUG_ON(inode->i_state != (I_FREEING | I_CLEAR));
in evict() because I_CLEAR is set in clear_inode().
Fixes: commit 3d48d9810de4 ("btrfs: Handle uninitialised inode eviction")
