ice: fix Get link status data length

Get link status version 2 (opcode 0x0607) is returning an error because FW
expects a data length of 56 bytes, and this is causing the driver to fail
probe.

Update the get link status version 2 data length to 56 bytes by adding 5
byte reserved5 field to the end of struct ice_aqc_get_link_status_data and
passing it as parameter to offsetofend() to the fix error.
