drm/panthor: Update panthor_mmu::irq::mask when needed
[ Upstream commit 8ba64cf2f358079d09faba7529aad2b0a46c7903 ]
When we clear the faulty bits in the AS mask, we also need to update
the panthor_mmu::irq::mask field otherwise our IRQ handler won't get
called again until the GPU is reset.
Changes in v2:
- Add Liviu's R-b
Changes in v3:
- Add Steve's R-b
Fixes: 647810ec2476 ("drm/panthor: Add the MMU/VM logical block")
