[PATCH 3/6] xen/common: grant_table: Avoid to shadow "frame" in __gnttab_map_grant_ref

[Julien Grall <julien.grall@citrix.com>]

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.
