To detect the timestamp mode configured on the NIC the mlx5 PMD uses the
firmware command ACCESS_REGISTER_USER.
The HCA capability command has an attribute flag checking whether
firmware supports the command.

However, the HCA capability query command read the flag from wrong place
in PRM structure.

This patch move the plag to correct place.
