    grant_table: avoid to shadow "frame" in __gnttab_map_grant_ref
    
    The variable "frame" is declared twice within the function
    __gntab_map_grant_ref.  This makes the code quite confusing to read.
    
    The second definition is not useful as the first one is never used
    until then. So drop it.
