Subject: [16/83] netback: remove redundant assignment

3.2.47-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Liu <wei.liu2@...rix.com>

commit 16ecba2605a3bbd374cd993e532264e2d8de49e5 upstream.

New value for netbk->mmap_pages[pending_idx] is assigned in
xen_netbk_alloc_page(), no need for a second assignment which
exposes internal to the outside world.
