cluster/afr: Pre-op should be undone for non-piggyback post-op
Problem: When fop fails post-op is always performed over the network irrespective of whether pre-op is piggybacked or not. Decrementing Pre-op-done count even for the piggybacked ones is wrong. I have added an assert for pre_op_done to be non-zero and when dd of=a if=/dev/urandom bs=5M count=1000 is executed and a brick is taken down, the mount is crashing. Fix: Decrement pre-op-done count only when the post-op is not piggybacked.
