cluster/afr: Filter O_TRUNC in afr-fix-open
RCA: When open was done while a brick is down, afr opens the file after the brick comes backup. If this happens after the self-heal on the file is completed by self-heald etc, the file will end up in truncated state. Fix: Filter O_TRUNC while afr-fix-open because afr_open turns O_TRUNC into truncate transaction, so there will be pending changelog for the subvolume on which open fails. Testing: Had to simulate the race by stopping fix-open until self-heald completes self-heal on the file after brick online.
