RISC-V: KVM: Propagate interrupted G-stage faults
__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.
