octeontx2-af: Fix key checking for source mac

commit c3c290276927a3ae79342a4e17ec0500c138c63a upstream.

Given a field with its location/offset in input packet,
the key checking logic verifies whether extracting the
field can be supported or not based on the mkex profile
loaded in hardware. This logic is wrong wrt source mac
and this patch fixes that.
