btrfs: remove shadowing variables in __btrfs_map_block
1) We can safely use the function's 'i'. Fixes warning
fs/btrfs/volumes.c:5257:7: warning: declaration of 'i' shadows a previous local
fs/btrfs/volumes.c:4951:6: warning: shadowed declaration is here
2) A local variable duplicates name of an argument, we can use the value
directly. Fixes warning
fs/btrfs/volumes.c:5433:8: warning: declaration of 'length' shadows a parameter
fs/btrfs/volumes.c:4935:27: warning: shadowed declaration is here
