--------------------------------
[ Upstream commit be93825f0e6428c2d3f03a6e4d447dc48d33d7ff ]
Variable cur_idx is being initialized with a value that is never read, it is being re-assigned later in a while-loop. Remove the redundant assignment. Cleans up clang scan build warning:
drivers/md/bcache/writeback.c:916:2: warning: Value stored to 'cur_idx' is never read [deadcode.DeadStores]
