afr: Ignore event_generation checks post inode refresh for write txns
Before http://review.gluster.org/#/c/15673/, 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. 15673 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().
