net/hns3: fix Rx with PTP

The Rx and Tx vector algorithm of hns3 PMD don't support PTP
function. Currently, hns3 driver uses 'pf->ptp_enable' to check
whether PTP is enabled so as to not select Rx and Tx vector
algorithm. And the variable is set when call rte_eth_timesync_enable().
Namely, it may not be set before selecting Rx/Tx function, let's say
the case: set PTP offload in dev_configure(), do dev_start() and then
call rte_eth_timesync_enable(). In this case, all PTP packets can not
be received to application. So this patch fixes the check based on the
RTE_ETH_RX_OFFLOAD_TIMESTAMP flag.
