Using "scontrol update job=10 priority=0" set the job in JobHeldUser/JobHeldAdmin state.

But if we use "scontrol update job=10 priority=10", of course priotity is not changed, there is no error.

Then with "scontrol release job=10", we can see the priority is reset to initial one, but not to 10.

Maybe an error can printed when trying to change the priority of an held job?
Something like:

@file job_mgr.c :
info("ignore priority reset request on held job %u",
job_ptr->job_id);
+ error_code = ESLURM_JOB_HELD;
