Masking HALP ICR should protect the driver from hitting the HALP ICR over and over again. However, in case there is another MISC ICR we will read the HALP ICR and issue a completion. This can lead to a case where HALP voting is completed immediately, as the completion is already set. Reinit the HALP completion before the actual vote will clear previous completions and protect from such cases.
