e1000e: Correctly include VLAN_HLEN when changing interface MTU
When changing the interface mtu, the driver starts with a value
that doesn't include VLAN_HLEN. Later tests in the driver
set the rx_buffer_len based on the mtu. As a result, when
the user increases the mtu to 1504 (to support 802.1AD for example),
the driver rx_buffer_len does not change and frames longer
the 1522 bytes are rejected as too long.
Include VLAN_HLEN from the start so that an user mtu greater then
1500 bytes is correctly reflected in the driver rx_buffer_len.
