ioapic_irqd_[un]mask() are misnomers as both functions do way more than masking and unmasking the interrupt line. Both deal with the moving the affinity of the interrupt within interrupt context. The mask/unmask is just a tiny part of the functionality.
Rename them to ioapic_prepare/finish_move(), fixup the call sites and rename the related variables in the code to reflect what this is about. No functional change.
