    afr: add errno to afr_inode_refresh_done()

    Backport of https://review.gluster.org/17413 and
    https://review.gluster.org/17436

    Problem:
    When parellel `rm -rf`s were being done from cifs clients, opendir might
    fail on some replicas with ENOENT. DHT ignores partial opendir failures
    in dht_fd_cbk() and winds readdirs on those replicas. Afr inode refresh
    (as a part of readdirp read_txn) sees in its fd context that the state
    of the fds is *not* AFR_FD_OPENED and bails out to
    afr_inode_refresh_done() without doing a refresh. When this happens, the
    errno is set as EIO due to lack of readable subvols, logging split-brain
    messages in the logs.

    Fix:
    Introduce an errno argument to afr_inode_refresh_do() to bail out with
    the right error value when inode refresh is not performed.
