ixgbevf: Return error on failure to enable VLAN
With recent kernel changes we can now return errors on a failure to setup a
VLAN filter. This patch takes advantage of that opportunity so that we can
return either an EIO error in the case of a mailbox failure, or an EACCESS
error in the case of being denied access to the VLAN filter table by the
PF.
