[net 7/7] net/mlx5e: Fix condition when retrieving PTP-rqn

[Saeed Mahameed <saeed@kernel.org>]

From: Aya Levin <ayal@nvidia.com>

When activating the PTP-RQ, redirect the RQT from drop-RQ to PTP-RQ.
Use mlx5e_channels_get_ptp_rqn to retrieve the rqn. This helper returns
a boolean (not status), hence caller should consider return value 0 as a
fail. Change the caller interpretation of the return value.
