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.
