irqchip/gic-v3: Add missing barrier to 32bit version of gic_read_iar()
Commit1a1ebd5
("irqchip/gic-v3: Make sure read from ICC_IAR1_EL1 is visible on redestributor") fixed the missing barrier on arm64, but forgot to update the 32bit counterpart, which has the same requirements. Let's fix it. Fixes:1a1ebd5
