net/mlx5e: Fix the presented RQ index in PTP stats

PTP-RQ counters title format contains PTP-RQ identifier, which is
mistakenly not passed to sprinft().
This leads to unexpected garbage values instead.
This patch fixes it.

Before applying the patch:
ethtool -S eth3 | grep ptp_rq
     ptp_rq15_packets: 0
     ptp_rq8_bytes: 0
     ptp_rq6_csum_complete: 0
     ptp_rq14_csum_complete_tail: 0
     ptp_rq3_csum_complete_tail_slow : 0
     ptp_rq9_csum_unnecessary: 0
     ptp_rq1_csum_unnecessary_inner: 0
     ptp_rq7_csum_none: 0
     ptp_rq10_xdp_drop: 0
     ptp_rq9_xdp_redirect: 0
     ptp_rq13_lro_packets: 0
     ptp_rq12_lro_bytes: 0
     ptp_rq10_ecn_mark: 0
     ptp_rq9_removed_vlan_packets: 0
     ptp_rq5_wqe_err: 0
     ptp_rq8_mpwqe_filler_cqes: 0
     ptp_rq2_mpwqe_filler_strides: 0
     ptp_rq5_oversize_pkts_sw_drop: 0
     ptp_rq6_buff_alloc_err: 0
     ptp_rq15_cqe_compress_blks: 0
     ptp_rq2_cqe_compress_pkts: 0
     ptp_rq2_cache_reuse: 0

     ptp_rq12_congst_umr: 0
     ptp_rq11_arfs_err: 0
     ptp_rq9_recover: 0

After applying the patch:

     ptp_rq0_packets: 0
     ptp_rq0_bytes: 0
