[PATCH] RISC-V: KVM: Fix check for local interrupts on riscv32

[PATCH] RISC-V: KVM: Fix check for local interrupts on riscv32

[Samuel Holland]

To set all 64 bits in the mask on a 32-bit system, the constant must
have type `unsigned long long`.

Fixes: 6b1e8ba4bac4 ("RISC-V: KVM: Use bitmap for irqs_pending and irqs_pending_mask")
