Subject: bnx2x: fix detection of VLAN filtering feature for VF

From: Michal Schmidt <[email protected]>

[ Upstream commit 83bd9eb8fc69cdd5135ed6e1f066adc8841800fd ]

VFs are currently missing the VLAN filtering feature, because we were checking the PF's acquire response before actually performing the acquire.

Fix it by setting the feature flag later when we have the PF response.
