Variable i is being assigned a value that is never read, it is being re-assigned later in a for-loop. The assignment is redundant and can be removed.
Cleans up clang scan build warning: drivers/block/xen-blkback/blkback.c:934:14: warning: Although the value stored to 'i' is used in the enclosing expression, the value is never actually read from 'i' [deadcode.DeadStores]
