btrfs: scrub: remove redundant initialization of increment 



increment is being initialized to map->stripe_len but this is never
read as increment is overwritten later on. Remove the redundant
initialization.

Cleans up the following clang-analyzer warning:

fs/btrfs/scrub.c:3193:6: warning: Value stored to 'increment' during its
initialization is never read [clang-analyzer-deadcode.DeadStores].
