Subject: [PATCH net 3/5] bnx2x: Fix functionality of configuring vlan
 list

From: Ariel Elior <ariele@...adcom.com>

The check on return code of bnx2x_vfop_config_vlan0() would lead to error
handling flow as the return value indicating an existing pending ramrod would
be erroneously considered as an error.
