There's an issue with the versions in that image. However, HP provides an updated Broadcom package at http://vibsdepot.hp.com/hpq/jul2014/esxi-550-devicedrivers/. After installing this package you will be able to apply updates again.
Btw. ESXi patches include all prior patches, so you don't have to apply both VMware patches. The latest one is sufficient.
