[dpdk-stable] [PATCH 19.11 6/9] net/bnxt: fix timesync when PTP is not supported

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

[ upstream commit ab15dd5a1c4d563e80b10e42e39c4d2f010fa389 ]

Fixed to return error when PTP support is not supported on the port.
Also, removed an unnecessary check inside bnxt_get_rx_ts().

Fixes: b11cceb83a34 ("net/bnxt: support timesync")
