genirq/migration: Avoid out of line call if pending is not set
The upcoming fix for the -EBUSY return from affinity settings requires to use the irq_move_irq() functionality even on irq remapped interrupts. To avoid the out of line call, move the check for the pending bit into an inline helper. Preparatory change for the real fix. No functional change.
