net/bnxt: fix VLAN antispoof configuration code

We are wrongly using a Rx side HWRM command set_rx_mask to configure
VLAN anti-spoof. This being a Tx side feature, this patch
tries to fix it.

Since the HWRM command to do it is available only in
the newer firmware versions, the patch verifies the firmware
version before attempting to send the HWRM command to
the firmware.
