    cluster/afr: Refresh inode for inode-write fops in need

    Problem:
    If a named fresh-lookup is done on an loc and the fop fails on one of the
    bricks or not sent on one of the bricks, but by the time response comes to
afr,
    if the brick is up, 'can_interpret' will be set to false in
afr_lookup_done(),
    this will lead to inode-ctx for that inode to be not set, this can lead to
EIO
    in case of a transaction as it depends on 'readable' array to be available
by
    that point.

    Fix:
    Refresh inode for inode-write fops for the ctx to be set if it is not
already
    done at the time of named fresh-lookup or if the file is in split-brain
where
    we need to perform one more refresh before failing the fop to check if the
file
    is still in split-brain or not.
