btrfs: abort transaction if we don't find extref in btrfs_del_inode_extref()

Browse Source 
When an extended ref is deleted we do a sanity check right before
removing the item, if we can't find it then handle the error. This is
done by btrfs_handle_fs_error() but this is from the time before we had
the transaction abort infrastructure, so switch to that. The end result
is the same, the error is reported and switched to read-only. We newly
return the -ENOENT error code as this better represents what happened.
