Subject: [PATCH] mtd: mtdswap: Remove redundant assignment of pointer eb

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

The pointer eb is being assigned a value that is never read, it is
being updated later on. The assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
