protocol: Fix 4.0 client, parsing older iatt in dict
In a mixed mode cluster involving 4.0 and older 3.x bricks, if clients are newer, then the iatt encoded in the dictionary can be of the older iatt format, which a newer client will map incorrectly to the newer structure. This causes failures in FOPs that depend on this iatt for some functionality (seen in mkdir operations failing as EIO, when DHT hits its internal setxattr call). The fix provided is to convert the iatt in the dict, based on which RPC version is used to communicate with the server. IOW, this is the reverse of change in commit "b966c7790e" Tested using a mixed mode cluster (i.e bricks in 3.12 and 4.0 versions) and a mixed set of clients, 3.12 and 4.0 clients. There is no regression test provided, as this needs a mixed mode cluster to test and validate.
