Subject: [PATCH 128/141] glusterd: Fix bulkvoldict thread logic in brick
multiplexing
Problem: Currently glusterd spawn bulkvoldict in brick_mux
environment while no. of volumes are less than configured
glusterd.vol_count_per_thread
Solution: Correct the logic to spawn bulkvoldict thread
1) Calculate endindex only while total thread is non zero
2) Update end index correctly to pass index for bulkvoldict
