[PATCH 2/4] target/riscv: cpu: Fixup local variables shadowing

[Alistair Francis]

Local variables shadowing other local variables or parameters make the
code needlessly hard to understand.  Bugs love to hide in such code.
Evidence: "[PATCH v3 1/7] migration/rdma: Fix save_page method to fail
on polling error".

This patch removes the local variable shadowing. Tested by adding:

    --extra-cflags='-Wshadow=local -Wno-error=shadow=local 
-Wno-error=shadow=compatible-local'

To configure
