IB/mlx5: Don't expose debugfs entries for RRoCE general parameters if not supported
[ Upstream commit 43fdbd140238d44e7e847232719fef7d20f9d326 ]
debugfs entries for RRoCE general CC parameters must be exposed only when
they are supported, otherwise when accessing them there may be a syndrome
error in kernel log, for example:
$ cat /sys/kernel/debug/mlx5/0000:08:00.1/cc_params/rtt_resp_dscp
cat: '/sys/kernel/debug/mlx5/0000:08:00.1/cc_params/rtt_resp_dscp': Invalid argument
$ dmesg
mlx5_core 0000:08:00.1: mlx5_cmd_out_err:805:(pid 1253): QUERY_CONG_PARAMS(0x824) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x325a82), err(-22)
