octeontx2-af: Update correct mask to filter IPv4 fragments

During the initial design, the IPv4 ip_flag mask was set to 0xff.
Which results to filter only fragmets with (fragment_offset == 0).
As part of the fix, updated the mask to 0x20 to filter all the
fragmented packets irrespective of the fragment_offset value.
