replicate: set read-child to the subvolume which replied first (fastest)
In the old logic read-child was set to the last subvolume which replied. Now it is updated to the first subvolume. This way we can ensure that local servers are preferred for reads _most_ of the times. Signed-off-by: Anand Avati <avati@gluster.com> Signed-off-by: Anand V.
