cluster/afr: Print heal info split-brain output in stream fashion

Problem:
When we trigger the heal info split-brain command the o/p is not
streamed as it is received, but dumped at the end for all the bricks
together. This gives a perception that the command is hung.

Fix:
When we get a split brain entry while crawling throught the pending
heal entries, flush that immediately so that it prints the output
in a stream fashion and doesn't look like the cli is hung.
