btrfs-progs: check: prevent attempt to insert extent record with max_size==0
When this happens, we will trip a BUG_ON(end < start) in insert_state
because in check_extent_refs, we use this max_size expecting it's not zero:
set_extent_dirty(root->fs_info->excluded_extents,
rec->start,
rec->start + rec->max_size - 1);
See https://bugzilla.redhat.com/show_bug.cgi?id=1435567
for an example where this scenario occurs.
