libdiskfs: Don't deadlock on cache lookup error.
If the filesystem returns an error we need to cleanup and avoid a deadlock.
This can happen if there is a disk corruption, or one has a stale ino (they
can get repurposed on restart)
Its easy to reproduce this bug by placing a 'poison' in
diskfs_user_read_node for a particular ino
and then just try to access the corresponding file from live system.
Before this fix:
- deadlock
With this fix:
- 'stat: cannot statx '<filename>': Input/output error'
