Subject: [PATCH][next] netfilter: nf_log_bridge: Fix missing assignment of ret on a call to nf_log_register

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

Currently the call to nf_log_register is returning an error code that
is not being assigned to ret and yet ret is being checked. Fix this by
adding in the missing assignment.

Addresses-Coverity: ("Logically dead code")
Fixes: 8d02e7da87a0 ("netfilter: nf_log_bridge: merge with nf_log_syslog")
