iavf: Add ability to turn off CRC stripping for VF

Previously CRC stripping was always enabled for VF.

Now it is possible to turn off CRC stripping via ethtool:

    #ethtool -K <interface> rx-fcs on

To turn off CRC stripping, first VLAN stripping must be disabled:

    #ethtool -K <interface> rx-vlan-offload off

if any VLAN interfaces exists, otherwise VLAN stripping will be turned
off by the driver.

In iavf_configure_queues add check if CRC stripping is enabled for
VF, if it's enabled then set crc_disabled to false on every VF's
queue. In iavf_set_features add check if CRC stripping setting was
changed then schedule reset.
