No, that should not be a unroll fix.
Currently there are no objects registered by the main nf_tables
module, so for nft_secmark_obj_type I had to introduce this new logic.

Aren't they helpful?
"invalid security context" can pop up if someone supplies an invalid
SELinux context (nft add secmark inet filter sshtag
\"this_is_invalid\") and uses it
"unable to convert security context" can pop up if no LSM is enabled
"unable to map security context" should never happen, but one never knows
"unable to obtain relabeling permission" can pop up if e.g. the
SELinux permission "kernel_t ssh_server_packet:packet relabelto" is
missing
