btrfs: handle invalid extent item reference found in check_committed_ref()

Browse source

The check_committed_ref() helper looks up an extent item by a key,
allowing to do an inexact search when key->offset is -1.  It's never
expected to find such item, as it would break the allowed range of a
extent item offset.
