1. kvserver: improve handling for removal of a replica, when multiple re… …

   …plicas already exist on the same node
   
   Fixes cockroachdb#60545
   
   The allocator in some cases allows for a range to have a replica
   on multiple stores of the same node. If that happens, it should allow
   itself to fix the situation by removing one of the offending replicas.
   This was only half working due to an ordering problem in how the replicas
   appeared in the descriptor. It could remove the first replica, but not the second one.
   
   Release note (bug fix): 20.2 introduced an ability to rebalance replicas
   between multiple stores on the same node. This change fixed a problem
   with that feature, where ocassionaly an intra-node rebalance would
   fail and a range would get stuck permanently under replicated.
