Subject: [PATCH] x86/boot/e820: remove a redundant self assignment

From: Colin Ian King <colin.king@...onical.com>

Remove a redundant self assignment of table->nr_entries, it does
nothing and is an artifact of code simplification re-work.

Detected by CoverityScan, CID#1428450 ("Self assignment")
