block/dirty-bitmap: Clean up local variable shadowing

Local variables shadowing other local variables or parameters make the
code needlessly hard to understand.  Tracked down with -Wshadow=local.
Clean up: rename both the pair of parameters and the pair of local
variables.  While there, move the local variables to function scope.
