[PATCH v3 5/7] block/vdi: Clean up local variable shadowing |
Date: |

Local variables shadowing other local variables or parameters make the
code needlessly hard to understand. Tracked down with -Wshadow=local.
Clean up: delete inner declarations when they are actually redundant,
else rename variables.
