__kvm_faultin_pfn() reports an interrupted host page fault with KVM_PFN_ERR_SIGPENDING. RISC-V currently handles it as a generic error PFN and returns -EFAULT. Return -EINTR for the signal-pending sentinel so callers can distinguish an interrupted fault from an invalid userspace mapping. Do not log the expected interruption as a vCPU exit error.
