    igc: Remove redundant IFCAP_VLAN_HWTAGGING check
    
    Match igb(4) as in f7926a6d0c10. From Vincenzo, this check is redundant
    to setup providing us an IGC_RXD_STAT_VP bit and would make for an
    unexpected condition if IFCAP_VLAN_HWTAGGING were not set but the tag
    was stripped, which would be passed up the stack breaking isolation.
