net/bnxt: fix check for PTP support in FW

[ upstream commit a642112 ]

On Thor, driver must use HWRM to access the timestamp information.
Driver should not advertise PTP support to application
if PTP information is not available via HWRM commands.

Fixes: 6cbd89f ("net/bnxt: support PTP for Thor")
