[PULL 18/38] migration/ram: Fix compilation with -Wshadow=local

[Juan Quintela <quintela@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

Rename the variable here to avoid that it shadows a variable from
the beginning of the function scope. With this change the code now
successfully compiles with -Wshadow=local.
