riscv: vector: allow non-preemptible kernel-mode vector with IRQs off

Browse source

Similar to commit 7137a203b2 ("arm64/fpsimd: Permit kernel mode NEON
with IRQs off"), we are upgrading get/put_cpu_vector_context such that
kvm_arch_vcpu_load/put can be safely called under both irq off and
regular process context.

Also, export both symbols so the kvm module can call into it.
