Since commit cd6438c5f844 ("iommu/rockchip: Reconstruct to support multi slaves") rk_iommu_is_stall_active() always returns false because the bitwise AND operates on the boolean flag promoted to an integer and a value that is either zero or BIT(2). Explicitly convert the right-hand value to a boolean so that both sides are guaranteed to be either zero or one. rk_iommu_is_paging_enabled() does not suffer from the same problem since RK_MMU_STATUS_PAGING_ENABLED is BIT(0), but let's apply the same change for consistency and to make it clear that it's correct without needing to lookup the value.
