ice: Use port number instead of PF ID for WoL

commit 3176551979b92b02756979c0f1e2d03d1fc82b1e upstream.

As per the spec, the WoL control word read from the NVM should be
interpreted as port numbers, and not PF numbers. So when checking
if WoL supported, use the port number instead of the PF ID.

Also, ice_is_wol_supported doesn't really need a pointer to the pf
struct, but just needs a pointer to the hw instance.
