ceph: fail the request directly if handle_reply gets an ESTALE

If MDS return ESTALE, that means the MDS has already iterated all the
possible active MDSes including the auth MDS or the inode is under
purging. No need to retry in auth MDS and will just return ESTALE
directly. Retrying in this situation will cause an infinite loop.

Also, retrying like this would prevent the kernel VFS layer ESTALE
handling from working properly. An ESTALE error is usually an indication
that the dcache is wrong, so we want to allow the VFS to redo the lookup
and revalidate it properly.
