net/bnxt: fix handling of VF configuration change

When there is a change in the default VLAN of the VF,
FW sends the VF_CFG_CHANGE async event to the driver.
Upon receiving this async event, driver currently only queries
the FW using HWRM_FUNC_QCFG. But this is not enough.

Driver has to clean up the existing filter and recreate filters
so the FW can apply the default VLAN to the filter.
