Subject: [PATCH][net-next] net: bridge: remove redundant check to see if err is set

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

The error check on err is redundant as it is being checked
previously each time it has been updated.  Remove this redundant
check.

Detected with CoverityScan, CID#140030("Logically dead code")
