[XEN PATCH 2/4] x86/emulate: move a variable declaration to address MISRA C:2012 Rule 5.3

[Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx>]

The declaration of local variable 'bytes' in 'hvmemul_rep_stos' causes
the shadowing of the same variable defined in the enclosing scope,
hence the declaration has been moved inside the scope where it's used,
with a different name.
