net: enetc: allow tc-etf offload even with NETIF_F_CSUM_MASK
The Time-Specified Departure feature is indeed mutually exclusive with
TX IP checksumming in ENETC, but TX checksumming in itself is broken and
was removed from this driver in commit 82728b91f124 ("enetc: Remove Tx
checksumming offload code").
The blamed commit declared NETIF_F_HW_CSUM in dev->features to comply
with software TSO's expectations, and still did the checksumming in
software by calling skb_checksum_help(). So there isn't any restriction
for the Time-Specified Departure feature.
However, enetc_setup_tc_txtime() doesn't understand that, and blindly
looks for NETIF_F_CSUM_MASK.
Instead of checking for things which can literally never happen in the
current code base, just remove the check and let the driver offload
tc-etf qdiscs.
Fixes: acede3c5dad5 ("net: enetc: declare NETIF_F_HW_CSUM and do it in software")
