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.
