Btrfs: fix extent state leak on failed nodatasum reads
When encountering an EIO while reading from a nodatasum extent, we insert an error record into the inode's failure tree. btrfs_readpage_end_io_hook returns early for nodatasum inodes. We'd better clear the failure tree in that case, otherwise the kernel complains about BUG extent_state: Objects remaining on kmem_cache_close() on rmmod.
