xen-netback: remove dead code
The array mmap_pages is never touched in the initialization function. This is remnant of mapping mechanism, which does not exist upstream. In current upstream code this array only tracks usage of pages inside netback. Those pages are allocated when contructing a SKB and passed directly to network subsystem.
