protocol/server: forget the inodes which got ENOENT in lookup
If a looked up object is removed from the backend, then upon getting a revalidated lookup on that object ENOENT error is received. protocol/server xlator handles it by removing dentry upon which ENOENT is received. But the inode associated with it still remains in the inode table, and whoever does nameless lookup on the gfid of that object will be able to do it successfully despite the object being not present. For handling this issue, upon getting ENOENT on a looked up entry in revalidate lookups, protocol/server should forget the inode as well. Though removing files directly from the backend is not allowed, in case of objects corrupted due to bitrot and marked as bad by scrubber, objects are removed directly from the backend in case of replicate volumes, so that the object is healed from the good copy. For handling this, the inode of the bad object removed from the backend should be forgotten. Otherwise, the inode which knows the object it represents is bad, does not allow read/write operations happening as part of self-heal.
