Subject: [PATCH][mtd-next] mtd: spi-nor: remove redundant check on err

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

The variable err is not updated since the previous check on it, so
the subsequent check on err is redundant and can be removed.

Detected by CoverityScan, CID#1448658 ("Logically dead code")
