net: gro: remove unnecessary df checks

Currently, packets with fixed IDs will be merged only if their
don't-fragment bit is set. This restriction is unnecessary since
packets without the don't-fragment bit will be forwarded as-is even
if they were merged together. The merged packets will be segmented
into their original forms before being forwarded, either by GSO or
by TSO. The IDs will also remain identical unless NETIF_F_TSO_MANGLEID
is set, in which case the IDs can become incrementing, which is also fine.

Clean up the code by removing the unnecessary don't-fragment checks.
