[PATCH] net/ice: fix ieee1588fwd not show PTP timestamp

[Simei Su]

For received PTP packets, the flag "RTE_MBUF_F_RX_IEEE1588_TMST" has not
been set which leads to received PTP packet not timestamped by hardware
shown in testpmd/ieee1588 fwd.

Fixes: 646dcbe6c701 ("net/ice: support IEEE 1588 PTP")
