In addition, mlx5_cmd_trigger_completions() is trying to trigger completion for MANAGE_PAGES command as well.

The issue arises because the PRMT is finding a block of type EFI_CONVENTIONAL_MEMORY, which is not appropriate for runtime services as described in Section 2.2.2 (Runtime Services) of the UEFI Specification [1].
