kvm: Move srcu_struct fields to end of struct kvm
Parallelizing SRCU callback handling will increase the size of srcu_struct, which will move the kvm structure's kvm_arch field out of reach of powerpc's current assembly code, which will result in the following sort of build error: arch/powerpc/kvm/book3s_hv_rmhandlers.S:617: Error: operand out of range (0x000000000000b328 is not between 0xffffffffffff8000 and 0x0000000000007fff) This commit moves the srcu_struct fields in the kvm structure to follow the kvm_arch field, which will allow powerpc's assembly code to continue to be able to reach the kvm_arch field.
