    afr: Ignore event_generation checks post inode refresh for write txns

    Backport of http://review.gluster.org/#/c/16205/

    Before http://review.gluster.org/#/c/16091/, after inode refresh, we
    failed read txns in case of EIO or event_generation being zero. For
    write transactions, the check was only for EIO. 16091 re-factored the
    code to fail both read and write when event_generation=0. This seems to
    have caused a regression as explained in the BZ.

    This patch restores that behaviour in afr_txn_refresh_done().
