LoongArch: KVM: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS
It doesn't make sense to return the recommended maximum number of vCPUs
which exceeds the maximum possible number of vCPUs.
Other architectures have already done this, such as commit 57a2e13ebdda
("KVM: MIPS: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS")
