cluster/afr: Fix incorrect logging in read transactions
afr_read_txn_refresh_done() at its entry point can fail for
reasons like ENOENT/ESTALE but seldom due to EIO, which is something
_AFR_ would internally generate and not receive in response from
a child translator. AFR is reporting "split-brain" for _any_
kind of failure in read txn, of the following kind:
[2015-07-07 18:04:34.787612] E [MSGID: 108008]
[afr-read-txn.c:76:afr_read_txn_refresh_done] 0-vol3-replicate-3:
Failing STAT on gfid 18a973c4-73d3-48b8-942c-33a6f1a8e6b4:
split-brain observed. [Input/output error]
This patch fixes such misleading errors.
To-Do:
Avoid logging EIO if/when split-brain choice is set.
Will do that as part of a separate commit.
